Testing HEPA filters with smoke and a small particle generator. H13 HEPA filters work better than True (H10-H1) HEPA filters. In short, HEPA filters capture very well small particles such as dust, pollen, mold, smoke, pet dander, etc. If the HEPA filter does not meet the DOE standards for HEPA filtration, then it is not considered true HEPA.
While the filter may still be able to capture 0.3 micron particles and capture a high percentage of them, unless true HEPA is confirmed, it cannot claim that it meets DOE HEPA standards. The main differences between the HEPA filter and the True HEPA filter are the filtration efficiency. In general, the HEPA-type filter has an efficiency rate of 99% for capturing particles as small as 2 microns. True HEPA filters the game with a better efficiency rate of 99.97% on particles as small as 0.3 microns.
As both filters are widely used in the air purifier industry, the HEPA-type filter is often combined with the most economical and compact air purifier. The true HEPA filter, on the other hand, is labeled with the largest premium air purifier. Medical-grade HEPA filters are the most effective method of air filtration. While True HEPA filters are rated H10 to H12, HEPA filters considered medical grade are classified as H13 filters.
These can remove up to 99.995% of particles down to 0.1 micron. As with True HEPA, medical grade filters must be rigorously tested before experts give them this rating. If you get the HEPA-type filter, you'll know how efficiently your air filtration device works and if you get clean air. A true HEPA filtration device or filter is the only HEPA filter that truly meets the DOE standard for HEPA filtration, has the highest efficiency and reaches the 99.97% threshold.
True HEPA: A consumer air filter labeled True HEPA must meet the DOE standard closest to the DOE standard for a HEPA air filter. True HEPA filters are a little more advanced, capturing up to 99.97% of particles measuring just 0.3 microns from the air. UltraHEPA: AirDoctor uses this marketing term, stating that its air purifier is “100 times more effective than HEPA air filters, capable of removing particles down to 0.003 microns in size. Note that in Europe, the HEPA standard is defined a little differently (if you see a filter with a rating similar to H13 or U16, the European standard is being used) in general terms, the higher the number (regardless of the letter), the better the filter according to the European standard.
Read on to learn more about the differences between different types of HEPA filters and why you should consider buying an air purifier with True HEPA. HEPA-type: Calling a filter a HEPA-type filter is essentially meaningless, since it doesn't conform to any standard. When looking for portable air purifier solutions for your facility, it's essential to know the difference between HEPA, true HEPA, HEPA-type, and other HEPA filters. The best way to know what type of HEPA filter is used in an air purifier is to review the specifications in its manual or website.
If an air filter claims to be a HEPA filter, you basically trust that the manufacturer had the filters tested and meet the DOE standard. Sanalife True HEPA portable air purifiers have multi-stage air cleaning power to provide the cleanest air possible. When air is directed to the HEPA filter, the high-density filter fibers trap contaminants that pass through Direct Impact, Diffusion, Screening, and Interception. Normal HEPA filter air purifiers are the least recommended, since particles of 1.99 microns or smaller are not removed.
Choosing a medical-grade H13 HEPA filter over less efficient variants can offer some notable benefits, especially compared to an air conditioner, since air purifiers work to clean the air. .
