The Best Air Purifier Tier List Version 2.0 - Surprising Results!

the lavoid core 300 is the most popular air purifier on the market today it's small light and cheap but it doesn't have a HEPA filter the core 300 clean the air in our test room in 22 minutes which is a good result for its size but our testing and really any testing you see on YouTube is limited to testing for larger particles we use a dilas dc100 pro for testing which only measures particles as small as 0.5 microns most other air quality meters only measure pm1 PM 2.5 or pm10 particles 1 Micron 2.5 microns or 10 microns in size HEPA filters capture particles larger and smaller than 0.3 microns with very high efficiency and YouTube test channels like us cannot test for efficacy at the lower end of this range the only way to know for sure that you're buying an air purifier that can properly filter ultra fine particles is to buy one with a certified laboratory tested HEPA filter and the core 300 doesn't have a certified HEPA filter it has a lower grade proprietary particle filter so it goes in the etier the lavoid core 400s and core 600s are basically larger higher air flow more energy efficient versions of the core 300 they move quite a bit more air through their filters in the core 300 and do so more efficiently but they both also don't have HEPA filters they have the same proprietary particle filter as the core 300 just a larger version of it with higher air flow and better Energy Efficiency we do put them in a a tier above the core 300 though in the d-tier the lavoid vital 200s has similar air flow to the core 400s and is also highly energy efficient one big upgrade you get with the vital 200s is a better quality pre-filter Core Series units have a lowquality mesh pre-filter that stretched right over the particle filter that stretched right over the particle filter that stretched right over the particle filter because of its proximity to the particle filter cleaning this type of prefilter can damage the particle filter the vital 200s adds a separate much higher quality pre-filter the vital 200s adds a separate much higher quality pre-filter
