Mounto 10-Pack Pre-Filter Replacements for HEPA 500 Air Scrubber, Enhanced Dust Capture, Easy Installation, Extends HEPA Filter Life

Works great. Remodeling and need this to remove drywall dust.

We use these filters in our job site airscrubbers.. Solid function on collecting the fine construction dust at a fair price.. We buy boxes of these.

I’m going to assume since the filters get clogged up so quick, they are doing what they are supposed to? We use it to filter out concrete dust when grinding or breaking concrete

Great aftermarket replacement comes with multiple filters you can’t beat it for a dust prefilter

This obviously fits other manufacturers "Air Scrubber HEPA 550" models but it does not fit a "ALORAIR CleanShield HEPA 550 Industrial Commercial Air Scrubber". That manufacturer(ALORAIR)/model(CleanShield HEPA 550) has a rectangular G3 pre-filter that is 13.7" x 14.88" x 1" in size. This pre-filter is a square G4 filter. This was recommended by Amazon at purchase time so I got them but they will not fit this manufacturers HEPA 550 model. The picture of the ALORAIR air scrubber looks identical to the others brands that do take this pre-filter. I suggest putting a better name and better description/details or others will make this same mistake. ALORAIR needs to update their product descriptions too.
