Everything about HEPA filter For Home Appliances: Why is it Important?

Who doesn’t want to breathe some fresh air? However, with the rising level of pollution in the world, fresh air is becoming scarce. This is where technology steps in with the HEPA filters.

But what is a HEPA filter?

The full form of HEPA stands for High Efficiency Particulate Air. As the name suggests, the filters work by getting rid of unwanted particulates from the air. As such, it is quite sought after by consumers today.

Let’s not mistake HEPA for an existing brand that manufactures the filters. It is more of a rating for filters that meet a certain standard. First conceptualized in 1940, HEPA rated filters are very efficient at their job, getting rid of 99% of the particulates.

You will find different types of HEPA filters in the market. Based on their efficiency, they have different levels of rating. When attached to household appliances, the filters purify the air of the room. The likes of these appliances include air conditioners, air purifiers, vacuum cleaners, etc.

At its peak performance, a HEPA filter eliminates 99% of smoke, pollen, dust, pet dander, etc. from the air. To be precise, all particulate with a diameter of 0.3 microns are effectively removed. This includes harmful bacteria and germs as well.

Types of HEPA filters

As mentioned before, HEPA is a rating based on the efficiency of a particular filter. Hence, there are different levels of it. These levels range from type A to F. Before we learn about these, let’s get a few things out of the way.

In the market, you may find filters rated “HEPA Type” or “HEPA Like.” Such products are only faulty and less efficient. The rating confuses the customers and tricks them y=into purchasing the models. But honestly, such products are not worth your money.

Filters rated as “True HEPA” or “Medical grade HEPA” are the most efficient ones of the lot.

  • Medical Grade HEPA is rated either H13 or H14. The H14 variant removes 99.995% of the particulates while the H13 removes 99.95%.
  • True HEPA is rated from H10 to H12. The efficiency of each variant increases gradually.

If these types sound confusing, there is a simpler scale. HEPA filters are also differentiated from Type A to Type F. The F variant is the most efficient by getting rid of 99.999% of the particulates having diameter 0.1-0.2 microns. The A variant is the worst of the lot as is not recommended for use.

Based on your requirements, you need to choose the ideal HEPA filter type. For more efficient working select Medical Grade HEPA filters or Type-F HEPA filters.
