Guides on Choosing A HEPA Air Cleaner 2017
What is The HEPA Air Filter? How Does A HEPA air Purifier Work?
HEPA is the abbreviation of High Efficiency Particulate Air, while the HEPA air purifier refers to the air purifier that contains a HEPA filter. And HEPA filter is able to capture particles as the air passes through it and is internationally recognized as the most efficient filter on particles removal. Air purifiers with HEPA filters are often recommended by many government institutions in America, like the Environmental Protection Agency and the American Lung Association. In this post you will find some best HEPA air purifier models and Reviews of HEPA Air Purifier based on consumer feedback.
True HEPA filters are up to 99.97% efficient at capturing airborne particles, as small as 0.3 microns or larger. These particles are about two hundredths of the diameter of a human hair. They are too light to fall down, so they are always floating in the air, damaging the air quality.
HEPA air purifiers are highly recommended by the allergists to their patients for the powerful capabilities. They can safely remove up to 99.97% of airborne particles and pollutants, even those at the molecular levels. Therefore, they can help people who have allergy or asthma to breathe easily, protecting them from the attack of contagious or other serious diseases.
How to Choose A Top Rated HEPA Air Purifier?
Although there are many great HEPA air purifiers in the marketplace, it’s unwise to buy a HEPA air cleaner by just depending on what it claims. If you do want to get a top HEPA air purifier that fits your needs most, following tips are better to know.
Must-to-have Filter: a medical grade HEPA filter
Air purifiers that contain medical grade HEPA filters are effective to remove particles. Generally, medical grade HEPA filters can eliminate up to 99.97% of airborne particles and pollutants, even down to 0.3 microns in size. This kind of filter is often used in hospital to provide the purest air. Air purifiers that don’t contain medial grade HEPA filters or utilize HEPA-like filters to build their air purification won’t get the same air quality as medical grade HEPA filters. In our articles today, we will also introduce some best rated HEPA air purifiers, you could choose one from them.
Imperative Filter: High Capacity Pre-filter
A pre-filter is mainly used to trap larger particles, like dust, pet fur, hair or lint, and is very necessary to extend the life of the HEPA filter. Usually, the HEPA filter is designed to capture the smallest airborne particles, but if it is directly used to filter all particles in the air, larger particles can potentially clog it and cause it to operate less efficiently, which shortens its life and increases the costs. That’s why a high capacity pre-filter is needed to prolong the life of your HEPA filter. In our HEPA air purifiers reviews, we have picked out the HEPA room air purifier with high quality pre-filter in the comparisons part of this article.
Invaluable filter: Activated Carbon Filter
An activated carbon filter can help air purifier to remove airborne chemicals or pollutants as they pass through it by attaching them to the pore of it. If the carbon is treated with oxygen, it will become more permeable. With an activated carbon filter, the air purifier can eliminate more impurities from the air.
Counterproductive Traits: Ozone and the Off-gassing of chemicals
The air cleaning process of some air purifiers may generate ozone as a byproduct. Ozone is a charged oxygen molecule that will become harmful in high concentrations. Ionizers are the most common air purifiers that can release ozone, because they usually use an electrostatic process to purify the air, which can release a clean and crisp smell. Unexpectedly, the smell is not the pure air, but the dangerous ozone. Therefore, air purifiers that can emit ozone should be avoided when choosing an air purifier.
Besides, air purifiers that are made with poor quality plastic also should be avoided since their plastic can often promote the off-gassing of chemicals, such as Volatile Organic Compounds (VOCs).
