Need we replace our air purifier filters on time and how often

In this article CLEAN will introduce why should we replace our air purifier filters on time,and how often should we replace the filters.

Why need to replace our air purifier filters on time?What will happen if we never replace them?


Replacing air purifier filters on time is important for maintaining efficiency, improving air quality, preventing health issues, and increasing the lifespan of the air purifier:


  • Maintaining Efficiency: The filter is the main component of an air purifier that traps pollutants and contaminants from the air. Over time, the filter becomes clogged with particles, reducing its effectiveness in removing pollutants from the air. By replacing the filter on time, the air purifier can maintain its efficiency and continue to provide clean air.
  • Improving Air Quality: A dirty or clogged filter can lead to poor air quality as it may release trapped particles back into the air. Replacing the filter on time ensures that the air purifier is capturing as many pollutants as possible, which can improve the air quality in your home or office.
  • Preventing Health Issues: Exposure to air pollutants can lead to various health issues such as allergies, asthma, and respiratory problems. By replacing the air purifier filter on time, you can reduce the risk of these health issues and ensure that the air you breathe is as clean as possible.
  • Increasing Lifespan of the Air Purifier: A dirty or clogged filter can put a strain on the air purifier’s motor, leading to increased wear and tear and reducing the lifespan of the unit. By replacing the filter on time, you can help to prolong the lifespan of your air purifier.


How long will our air purifier filters last,and how often to replace them?


The lifespan of an air purifier filter depends on various factors such as the type of filter, the air quality in the room, and the usage frequency. Here are some general guidelines for how long different types of air purifier filters last:

  • HEPA Filters: HEPA filters can last anywhere from 6 months to 2 years depending on the air quality in the room and how often the filter is used. It’s recommended to replace HEPA filters every 12 months to maintain the effectiveness of the filter.
  • Activated Carbon Filters: Activated carbon filters can last up to 6 months, but it’s recommended to replace them every 3 months to ensure maximum effectiveness in removing odors, chemicals, and gases.
  • Pre-Filters: Pre-filters are the first line of defense for an air purifier and capture larger particles such as dust and pet hair. They usually last about 3 months before needing to be replaced.

It’s important to follow the manufacturer’s recommendations for filter replacement as a clogged or dirty filter can reduce the effectiveness of an air purifier and lead to poor air quality. Some air purifiers also come with filter replacement indicators to remind users when it’s time to replace the filter.


Why Is It Beneficial To Use General Ventilation Filters To Get A Clean Air Supply?

Fresh air is essential to humans in order to survive and no one can deny this fact. We would be constantly breathing in clean, pure air if we were living in an ideal world but unfortunately, that is not true.

Our jobs and the climate that we live in are the factors that help in determining that we will be spending a lot of our time indoors which ultimately provokes the need for a good ventilation system.

You should always buy your air filters from a trusted air filter manufacturer so that you don’t end up with a product that is just wastage of money.

Why is Ventilation Important?

In order to understand general ventilation filters. It’s important to address what ‘ventilation’ actually means. Ventilation is a process by which clean air is intentionally supplied to a space and the stale air is removed. Different types of ventilation systems such as air conditioning, air curtains, air recirculation, and air infiltration can be used.

Ventilation plays a very important role in commercial and industrial spaces that require controlled indoor air quality by diluting and displacing indoor pollutants. Ventilation is also used to control temperature, humidity, and air motion.

Benefits of a Good Ventilation System

  • Helps in Controlling Impurities – One of the biggest benefits of using a good ventilation system is that it helps in controlling impurities. If you feel like the air quality where you live isn’t great, especially in a bustling city centre, the air inside is more polluted than the air outside. A good ventilation system is very beneficial as it helps in expelling a build-up of pollutants, bacteria, moisture, and unpleasant odours.
  • Air Regulation – Unless you have a good ventilation system in place, you will not have any control over the air flow in your building. Too much fresh air means costly energy bills, this is the reason why good ventilation helps in controlling the air quality, while also regulating the required health and safety levels.
  • Reduce Temperatures – When there are lots of people gathered in a small and confined space, the environment becomes very hot and stuffy. A well-ventilated room can instantly help you make yourself more comfortable by creating a more relaxed environment, while will also make for a very productive workplace.
  • Health Benefits – Another benefit of good ventilation systems is the positive impact it creates on our health and well-being. Indoor air pollution coupled with bad ventilation can lead to several health problems such as headaches, allergies, asthma, rashes, and sinusitis. These health issues can be avoided with the help of the installation of a good ventilation system.


Depending on your place of work, we spend a great deal of time indoors in poorly ventilated spaces which can be very poor for our health. If you are someone who is spending a large amount of your working time in these spaces, this can be very bad for your health. This is the reason why it is so important to have well-ventilated rooms both at home and in the workplace. Fan filters are also very useful for clean air supply and this is the reason why you should find a good fan filter unit manufacturer so that you can have a 100% genuine product.

4 Different Types Of Industries Using Clean Room Filters

Air purifier filters are found in nearly every industry; the type of filter being used depends on the products that are being manufactured in that particular industry and the degree of purity expected. Products that require extreme levels of purity and ultra-filtration are manufactured or assembled in clean rooms.

What are Clean Room Filters?

Clean rooms are a technology that makes sure that there is a controlled level of contamination designed to maintain pollutants such as dust, airborne organisms, aerosol, or vaporized particle levels on a per cubic meter molecule measure.

To achieve this, air cleanings filtration devices, such as HEPA filters, and ultra-low particulate air (ULPA) filters are installed in the clean room walls and ceilings so that they can be completely pollutant free.

  • Pharmaceuticals Industry – The prerequisites in the pharmaceutical industry are disinfestations and good quality air. Thus, a clean room provides a controlled environment that makes sure sterile drugs, vaccines, and biomedical devices that are completely and 100% safe for the human body. This is the reason why the packaging of medicines should be done in separate clean rooms so that the scope of contamination can be reduced.
  • Laboratories and Research Facilities – Some science experiments are highly sensitive and this is the reason why they require the utmost cleanliness. Clean rooms are very beneficial as they provide a highly class-controlled environment that is appropriate for a high-class science experiment. In the case of laboratory clean rooms, though much effort is spent on aesthetically pleasing designs, equal emphasis should be paid to the airflow requirements that do not hamper the working of the laboratory.
  • Food Industry – Most food manufacturing companies and farms are leaning towards using clean room filters so that they can serve hygienic quality food to their customers. This way the food also gets a longer shelf life because they are free from any type of contamination.

In the food industry, there are choices of hard wall and soft wall clean rooms. Small, enclosed clean room units like ‘mini environments’ or ‘flow boxes’ with food-grade compatible lighting and portability benefits are usually preferred by food processing clients.

  • Cosmetics and Perfume Industry – As cosmetic products come in direct contact with the human body, cosmetics products should be produced in conditions that are close to medical manufacturing units. Cosmetic producers keep their main focus on controlling the contamination of their products. This is the reason why sterilization from the start to end of the cosmetic production cycle is a much-recommended.


Clean room filters are widely used in different types of industries because of the amazing benefits that it provides. You can find a lot of air filter suppliers all over the world but finding someone who delivers good quality products at reasonable prices should be your topmost priority.

How The HEPA Filters Are Beneficial At The Time Of COVID-19?

The development and innovations in the functions of air-cleaning technologies play a very important role when it comes to airborne infection control.

Air filtration uses high-efficiency particulate air (HEPA) because they are the most effective of filters. The role of a HEPA filter in the time of COVID-19 is that the air cleaner with a HEPA air purifier filter removes infectious viruses like SARs-CoV-2 from the air continuously depending on the running time manner.

As the HEPA filter is coated with an antiviral agent so it enhances the performance of the air cleaner. The antiviral agent consists mainly of monovalent copper components. The study proves that the version of HEPA-filtered air cleaners is worthwhile when preventing the spread of COVID-19.

Benefits of HEPA filter in the times of COVID-19:

When appropriately utilized, air cleaners and HVAC filters can aid in lowering the number of airborne pathogens, such as viruses, in a structure or small area. Air purification or filtration cannot entirely shield people from COVID-19. Filtration can be an element of a strategy to lessen the possibility of COVID-19 transmission indoors when used in conjunction with other best practices advised by the CDC and other public health organizations, such as social seclusion and mask use.

HVAC filters and air cleaners are made to remove contaminants from the air that travels through them. Air filtration and cleaning can aid in lowering airborne pollutants, such as virus-carrying particles.

How Do HEPA filters work?

It is not a process when the contaminated air passes through the HEPA filter, it is a three-step different process, after going through these three steps the contaminated air convert into filtered and healthy air. So let’s discuss these three-step processes which the contaminated air goes through.

  1. Interception: This process specifically works for larger particles. These larger particles such as dust and dirt, and many more particles whose size is more often more than 0.3 microns. These particles whose size is more than 0.3 microns will come in contact with glass fibers, these fibers use for trapping these particles. In simple words, the role of this step is that traps the large particles with the help of the glass fibers.
  2. Inertial Impaction: The direction of the air can be easily diverted depending on the path of flow. And when the air goes through the filter it tends to move in the same direction as a flow of the path and dust particles adapt in the same direction as the flow of the air due to the phenomenon which is known as the inertia of motion. So due to this phenomenon, the glass fibers will trap and hold the particles.
  3. Diffusion: the size of the particles is often less than or equal to 0.1 microns ( for example: viruses), these particles follow the Brownian motion. In simple words, there are molecules present in the air whose size is less than 0.1 microns. When the size and as well as mass of the particles are very small, the movement of the particles in a random direction will be caused by the collision of the particles with the air molecules. Since the particles whose size is less than 0.1 microns move in a random direction or in a zigzag direction, the movement of the particles in the random direction makes this process easy as it becomes easy to trap these particles by the filter.

So this is how these HEPA filters work and help to filter the contaminated air. The HEPA filters come in various types like a mini pleat HEPA filter, etc.


The acronym HEPA stands for “high-efficiency particulate air”. HEPA is a type of plated mechanical filter. This type of filter is used to remove up to 99.97% of dust, pollen, mould, bacteria, and any airborne particles with a size of 0.3 microns. No matter what the size of the particle is, it is all trapped by the HEPA filter. When you consult a quality HEPA filter manufacturer, they will tell you that with proper cleaning and timely filter replacement, HEPA filters can capture particles between 0.3 to 10 microns.

Reasons to Install HEPA Air Filters

1. Naturally Treats Allergies – Some allergies can cause a variety of health risks as well as discomfort for you and your family. If you are prone to allergies then you should know that the poor indoor air quality makes it even worse. What’s worse is that if you have serious health conditions like asthma then contaminants such as dirt, dust, pollens, dander, and other small particles can aggravate your allergies. HEPA filters are used to trap allergens which will reduce your symptoms and hopefully the health of everyone in your household will improve.

2. No By-products – The reality is that normal air filters emit hidden harmful by-products into your indoor air. This is why HEPA air filters are the best as they do not emit any type of by-product. HEPA filters are designed in a way that they work efficiently without generating any by-products. These filters are environment-friendly making them 100% safe to use.

3. Easy Accessibility – HEPA filter systems are easily accessible to the public which means you can easily find HEPA systems in various home appliances, such as air purifiers, humidifiers, vacuum cleaners, plumbing vents, etc. Just be very careful that you are purchasing from a reliable source.

4. Works Amazing For Newborns – Parents should definitely consider buying a HEPA filter system so that they can protect their infants from any kind of allergies. HEPA filters purify the air and also help in preventing respiratory infections. Allergies are more prevalent among newborns as their lungs are more vulnerable as compared to adults. By using HEPA air filters you can help your newborns stay away from all types of allergies.

5. Minimizes the Impact of Smoking – If someone in your family smokes then you should definitely install an air filter. A HEPA air filter works best in this scenario by removing smoke particles and all types of contaminants from the air. Smoking makes the air polluted which brings your family members at higher risk because it greatly affects babies and elderly people.

Air cleaning devices can improve your overall indoor air quality which ultimately reduces the risk of all types of allergies. The best way to reduce the number of contaminants in the air is by using a HEPA filter system. These systems will not only clean your indoor air but also make your house safe and allergens-free. Many air filter manufacturers sell HEPA filters but you should be careful while purchasing because you don’t want to end up having a filter that does not do what it claims.


Pocket bag filters are used as first or second-stage filters in air conditioning systems. If the air of the environment is not strict then these pocket filters are used as final filters. The air processed by pocket filters is absolutely clean and can be supplied to the people directly which is why pocket filters should be replaced frequently.

They are considered as one of the best filter structures at present because they are ideal for high-humidity environments. These filters are anti-rust and are used in a moist environment.

Advantages of Using Pocket Bag Filters

When talking about industrial air filtration systems, the conversation always centers on HEPA air purifiers, ionic air purifiers, and ozone air purifiers. These systems help by making a basic set of technologies behind industrial air purification.

While these are important to understand but none of these technologies can work well without the proper support of pre-filter. Pre-filters are designed to capture particles from the air that are larger than 5 microns. This is where bag filters come in handy as they are the primary filters that capture much smaller particles to make sure they work efficiently.

1. Increased Efficiency – Pocket filters are very beneficial as they help to increase the efficiency of an HVAC system. The better the quality of the air passing through your equipment, the fewer the chances that there will be something wrong. Pocket filters keep HVAC equipment from having to work too hard to provide a comfortable indoor environment. This is the reason why the chances to spend money on an unexpected repair will be reduced to the minimum.

2. Health Considerations – Airborne pollutants can cause some serious problems to your health which can reduce workplace productivity and worker satisfaction. Therefore, the quality of the air in your commercial building should be considered one of your top priorities.
With the help of pocket filters, a lot of harmful pollutants can be eliminated, helping to keep your workers healthy and productive. These filters also keep noxious fumes and odors away from the building so that it does not cause any harm to your workers and customers.

3. Suitable For a Host of Applications – Durable and high-efficient pocket filters are perfect for many types of different settings. These include schools, restaurants, hospitals, and many others. Pocket filters are compatible with most HVAC systems. Pocket filters trap all the dangerous contaminants that may cause serious problems to you, your workers, and your customers.

Many air purifier filter manufacturer claims that they provide filters that can remove up to 99% of the pollutants from the air but you should go for the pocket filter as it protects you from carbon dioxide emissions and humidity. These filters ensure that pollutants are diluted and removed from the building through a proper system of ventilation.

Advantages of an Air Purifier

Essentially, air purifiers work by cleansing the air, which could contain pollutants, allergens, and toxins. They accomplish the exact opposite of what humidifiers and essential oil diffusers do, which is to add particles to indoor air. Additionally, filters operate differently from air purifiers. Filters only remove particles, however, purifiers can also clean them.

Below are the Advantages of an Air Purifier:
Air purifiers come to include a fan and one or more filters. The fan (or occasionally a system of internal fans) draws air in, which then passes through the inner filters. These filters trap pollutants like dust, pollen, and bacteria while recirculating clean air into space. This filtering process maintains a healthy airflow inside.

Take steps to remove dangerous substances from indoor environments:
The air in your home may still be polluted with toxins from different cleaning products even if you don’t live in a large city with a lot of traffic. Many widely used household cleaners have dangerous ingredients like phthalates, chlorine, and ammonia. Small levels of exposure to these chemicals might not be harmful, but repeated exposure can result in serious health issues such as tumors, cancer, cardiovascular issues, and abnormalities of the nervous system.

Air purifiers that use activated carbon can eliminate these chemical contaminants, reducing the risk of many health problems. To remove impurities and recycle clean air back into space, this carbon filtering technology makes use of an extremely porous kind of carbon.

Eliminates offensive odors:
Many chemicals, including formaldehyde, benzene, and gasoline, break down and emit scents when left at room temperature. Paints, aerosol sprays, upholstered furniture, and air fresheners frequently contain volatile organic compounds (VOCs), as they are also referred to. You may experience nausea, shortness of breath, and even cognitive impairment from the scent of VOCs.

Other NIH studies show that ambient air with lower VOC levels improves function and output. Air purifiers with HEPA and activated carbon filters are good at trapping gases as well as particles to reduce pollution in the indoor environment.
If you have company around, you won’t have to worry about the smoke bothering them or the scent of cooking oil and spices. The air cleaners remove

Lowering the likelihood of airborne infections:
The flu and the common cold are airborne illnesses that are spread by circulating microbes. After one family member develops the flu, it’s not uncommon for other family members to fall ill. This occurs because everyone is breathing the same contaminated air that is full of bacteria and viruses.

Air purifiers with HEPA filters are able to get rid of these bacteria and viruses. You may safeguard yourself and your family by removing the cause of airborne diseases. If you live with young children, the elderly, or anybody else who has a weakened immune system, air filters are a need.

Increased sleep:
Indoor allergens that can lead to hay fever or allergies include dust mites, bacteria, and fungi. Hay fever-related runny noses can linger for up to several weeks. You may experience frequent sneezing, coughing, nose congestion, watery eyes, and sore throat as a result of allergies.

You become sleepy during the day and are less productive in the morning if you don’t get enough sleep. The bulk of allergens are removed from your home by HEPA air purifiers, preventing these sleep interruptions, therefore using them is preferable. When the air is clearer, you get a better night’s sleep.

Increased life expectancy:
Indoor air pollution may have an effect on your nervous system, cardiovascular system, and even respiratory system. The fumes and chemicals from common household items might irritate your lungs. Since airborne particles are so small and may cross the blood-brain barrier, they truly have an impact on your brain and cognitive functions.

Even microscopic particles will be captured by a good air purifier, enhancing the quality of the air you breathe.

I hope this blog is useful for you and you got all the information about air purifiers and why you should have one in your house or the place you work. It does just not purify the air but your life. There are many other filters that you can at least give a look at like the mini pleat HEPA filter. Drop your reviews about air purifiers and your experience of how they helped you in your life.
