Now question is that what is HEPA filter and what particles it captures and what not?


Essentially, the HEPA filter is a special type of air filter that captures microscopic particles. These particles include things like:

  • Dust
  • Pollen
  • Pet Dander
  • Smoke
  • Bacteria
  • Mold Spores and
  • Particulate matter that comes with outdoor air pollution.

And they also prevent them from floating around your home.

As the name suggests, HEPA air cleaners are devices that clean air by removing microscopic contaminants. As a result, this leads to a cleaner and fresher air for you to breathe.

Moreover, HEPA air purifiers are not only great for people with allergies or asthma but also those who enjoy healthier living and desired clean home.

The only weak factors to the HEPA air cleaners is that they cannot trap too small particles these are:

X Viruses

X Odors and 

X Chemical gas

Removing these small particles requires another type of filter to trap them.

Recommendation for filter

An air purifier that has a permanent filter can be washed and reused. However, only the smaller air purifiers use washable and reusable filters. 

Also, the air purifiers used for large spaces always use a reductive HEPA filter and needs to be replaced when it gets too dirty for being able to filter again properly.

We just simply gave the recommendation.

Various types of HEPA filters:

Another thing about HEPA filters is that they come in various types. When shopping the HEPA air purifier, remember the four points. These points are:

  1. True HEPA
  2. HEPA (plain old HEPA filter)
  3. HEPA- type
  4. HEPA- like

The difference between them is huge. 

Going to these details…

True HEPA: This is the best type of HEPA filter because it traps 99.97% of particles as small as 0.3 microns in size. And the true HEPA filter captures the widest range of contaminants. That is why it is the best type of HEPA filter. Isn’t it!

On the other hand, these HEPA-type, HEPA-like, and HEPA filters can capture fewer contaminants. Besides, they capture particles that are 2 microns or larger too. And this device fails to find pollutants that are far from the unit. It is a big difference in performance compared to the True HEPA filter.

So, the best device you can get is only by buying an air cleaner that uses a True-HEPA filter. These are worth the money if having the cleanest air possible in your top preference. 

Is HEPA air purifier effective for Coronavirus(COVID-19)?

Now, the world is passing the Epidemic period because of the coronavirus. COVID-19 spread through the air. An air purifier with HEPA filtration efficiently capture particles which are far smaller than virus. Since we are writing the air purifier so frequently, many readers have asked whether air purifiers can help with the COVID-19 issue. 

The answer is yes, in theory, but as of July 2021, you can remember that it has been unclear how much impact the machines causes. The researchers have expressed facts that the virus may be transmitting through the air or in other ways. And a significant number of experts argued in a letter to the WHO that the virus is airborne from that onwards the WHO has begun to accept the possibility. 


Back to purifiers: COVID-19 that comes to the virus is approximately 0.125 micron(125 nanometers) in diameter. The good news is that HEPA filters capture with extraordinary efficiency: 0.01 micron (10 nanometers) and above. Although many media outlets published incorrect news that HEPA filters don’t filter below 0.3 microns. That’s wrong.

But NASA’s study of HEPA filtration is quite technical but the graph on page 7 and the preceding paragraph do a great job of explaining ultrafine particles below the 0.3-micron HEPA test standard.

Moreover, that doesn’t mean than an air purifier will protect you or me. According to the CDC report published on June 16, 2021, is the coronavirus is primarily transmitted by person-to-person. And by contact with virus-laden droplets expelled through coughing and sneezing. Where the definition “airborne” gets tricky.

We can just give the recent evidence as we report on this topic in real-time. In this situation, we can’t something extra. But only HEPA purifier will be marginally useful in the fight against coronavirus.

Some tips to save from COVID-19

As it is the epidemic for the world and hasn’t any medicine against coronavirus. We recommend that you should follow the CDC’s advice. What is that advice? Advice is that:

  1. Should keep social distancing
  2. Washing your hands frequently 
  3. Wearing a face covering outdoors and
  4. Treating frequently touched surfaces with disinfectants.

Price of air purifiers

Lastly, remember that don’t worry about the price of air purifiers because it depends on how much you want to cleaner and fresher the air space will be around your home. And air purifiers provide you the more advantages to the cost. You can get a low price, medium price, and high price air purifiers out. Just choose!
