How To Clean Hepa Filter Honeywell Air Purifier
Can y'all clean a HEPA filter? If so, how should y'all launder or make clean a HEPA filter?
These questions go on cropping up, equally they're just about the only remaining problem for HEPA filters.
HEPA filters are nigh perfect: they are backed by tons of scientific tests; they're pretty cheap; they use most every bit much energy as a lightbulb; and they even have documented health benefits. But replacing them as opposed to washing them isn't ideal. It would exist great if we tin can clean and wash and re-employ HEPA filters.
Some 'Experts' Say Yous Tin Clean HEPA Filters
On the question-answer site Quora, I've seen industry insiders say you tin clean HEPA filters past banging the HEPA filter to go the dust out:
Some people even say y'all can clean HEPA filters by vacuuming them:
…or even by washing HEPA filters with water. Still other experts say you can NEVER clean HEPA filters.
Simply one affair I haven't seen is anyone actually exam the question and present the information. To go to the bottom of whether nosotros should clean HEPA filters, and the all-time fashion to clean them, Smart Air engineer CK tested washing and cleaning HEPA filters in the Smart Air lab.
When you search for "how to clean HEPA filter," you lot will see 2 methods to clean HEPA filters: vacuuming and washing. Smart Air put both of these to the exam.
one. Cleaning HEPA filters by Vacuuming
The commencement test we tried was vacuuming HEPA filters. Nosotros took a muddied HEPA filter, ran tests on its operation before cleaning, vacuumed information technology, and so ran more functioning tests afterwards cleaning information technology. In all, viii dirty HEPAs which had been used for iii-4 months in Beijing air were tested.
Testing Effectiveness of Vacuumed HEPA Filters
For each cleaning method, CK ran iii types of tests to measure the performance increase or decrease in the HEPA filter before and after cleaning. CK tested:
- Particle Capture: To see how cleaning the HEPA filter impacted capture performance, the pct of 0.iii micron particles by the HEPA was measured before and after cleaning. 0.3 micron particles are a neat benchmark considering they are the hardest particle size for HEPAs to capture.
- Air Flow: The amount of air traveling through the HEPA filter before and after cleaning can tell us if the HEPA filter is less clogged, or if the fibers in the HEPA filter have been damaged due to washing.
- CADR: CADR is the 'gold standard' for measuring an air purifier's performance. It measured the total combined impact (particle capture + air flow) of washing on the HEPA filter
Here'due south how the viii HEPA filters that were vacuumed performed earlier and after cleaning:
Should Yous Vacuum HEPA Filters: Results
On boilerplate, vacuuming increased CADR by about x%. Just in that location was also a lot of variance, ranging from a xiv% increase to a 3% decrease. Based on that data, cleaning a HEPA by vacuuming might help a little, simply there's as well a decent take chances it'll do aught at all, or it could fifty-fifty damage your filter.
What'southward The Vacuum Doing to the HEPA Filter?
HEPAs are made of thin fibers. The vacuum is probably pulling out some of the larger dust particles from the HEPA filter, but at the same time some of these fibers as well. You tin meet what looks like fibers that have been pulled loose in this motion-picture show.
Vacuuming bottom line:There may exist a slight benefit of vacuuming HEPAs, but the benefit is small, and it tin can too damage the HEPA. Therefore, we practise non recommend vacuuming.
ii. Cleaning HEPA filters by Washing With Water
Vacuuming did very lilliputian to improve the HEPA filters' effectiveness. Then, how about washing HEPA filters instead? This fourth dimension, CK tested 3 HEPA filters past washing them under a shower caput (with h2o only) and then leaving them to dry for a day.
Should You lot Wash HEPA Filters With H2o: Results
I stopped testing after 3 trials because the results were so conclusive: washing HEPA filters with water decreased effectiveness past an boilerplate of 32%.
Why Is It Bad to Launder HEPA Filters?
To become to the bottom of why washing was so bad for the HEPAs, I looked at wind speed and particle capture earlier and later washing.
Beginning, washing actually increased the corporeality of air passing through the HEPA filter.
Not bad, right!? But then the particle capture of the HEPA filter actually went downwards a lot afterwards washing.
Washing the HEPA filters probably broke some of the fibers or made the gaps between the fibers larger. That would explain why more air passed through after washing, just also more than particles!
Washing bottom line:Washing HEPA filters with water significantly decreases performance.
Bottom Line: How to Clean and Wash a HEPA Filter?
- Vacuuming HEPAs may improve performance, but the upshot is small.
- Washing HEPAs strongly decreases performance. We do non recommend washing HEPAs.
Therefore, HEPA filters should still be replaced when it starts to get clogged and its effectiveness dropped. When is this? Learn why the standard numbers might not ever be accurate.
