Are you looking to buy an air purifier? You might surely be surrounded by a myriad of choices. HEPA filters are one of the best air filters available in the market today. From vacuum cleaners, air purifier to a furnace and Air Conditioner Filters, HEPA filter is used everywhere.
HEPA, High-Efficiency Particulate Air is widely accepted as the best air filters. HEPA filters can eradicate 99.97% of particles which are bigger than 0.3 microns in diameter. These particles are so small that they are invisible to eyes and easy to inhale. HEPA filter can eradicate these particles before we inhale them.
Nowadays, any filters that can meet these standards are labelled as HEPA filter. But, beware of imitators. Many filters named as HEPA-like or HEPA-type is not actual HEPA filters. They are usually only 85-95% efficient, as compared to actual HEPA filter.
HEPA filters are too efficient at removing particles from the air and can also get rid of some biological organisms. They are not so popular in alleviating chemicals and odours. These filters eradicate the three main causes of allergies: dust, pollen and dander.
The contaminated particles are removed out in the following ways:
- Impaction – Large particles usually travel in a straight path which collides with the filter fibre and eventually stick to it.
- Sieving – The particle that moves away due to air flow gets stuck between the two fibres as the particle is larger than the gap.
- Interception – Medium-sized particles that re-route around the fibres eventually get stuck to the filter due to inertia
- Diffusion – As small size particles usually move at a faster rate, they easily get stuck to the fibres.
One important thing that you need to remember here is that a HEPA filter cannot clean the air that goes through it. You need to ensure that the purifier has a strong fan. Another problem air purifiers have is by-passing air. This is when the air can go around the filter and leave the air purifier without being cleaned. This is usually a problem in lower quality machines. Ensure to get a high-quality air purifier, so you don’t have to face this issue.
These filters are ideal for people with allergies or asthma. They eliminate most of the things that cause sneezing and cough. Usually, they are also asthma triggers. As HEPA filter doesn’t work well for chemical and odours, HEPA Filters are often combined with an activated carbon filter.
