YOU GET WHAT YOU PAY FOR.WIFE NOTICED IMPROVEMENT-LESS DUST.

This was supposed to filter away smoke, at MPR 1900. One of my neighbors is an old woman, and she burns her trash several times per week (!). I asked her to stop doing it, but with no effect. I live in Hong Kong, and some older people just burn everything, rather than recycling it or taking it to the trash. Her smoke goes into my HVAC system, and the whole house smells. I got these filters expecting to capture the smoke. It likely captures some of the smoke content, but not the smell. The whole house still smells like a campfire every time she burns her trash. Maybe I was just expecting too much. Maybe I need to add an active carbon filter?

WOW! First let me say, I have horrible allergies and sinus problems. I usually have a air purifier and Humidifier running to keep the air clean and not to dry. I was looking for a filter to help filter out more allergens because despite the air purifier I still found myself having sneezing fits in certain areas of my apartment, not to mention the filters at my apartment look like they cost 20 cents...flimsy green pads with a cardboard edge. Anyway, i digress. These are awesome. I replaced the filters and almost immediately noticed a difference. The first 2 pictures show a brand new filter, the last 2 show after 3 months use! Im cant believe I had been breathing all of that in. I will definitely continue to buy these.

Good filters at great price

High level of filtration.

This is a very high quality product, but you pay a premium for that quality. A less expensive brand will do the same job for about half the price or more.

Good quality

these filters came removed from the factory packaging and actually had a bug stuck in one of the folds in the filter as if they had been used for awhile so for the value Did i get what i paid for ???

Recently moved out of a mold infested apartment. These filters give me peace of mind that I don’t have to worry about being contaminated again. They’re pricey but when you think about having to throw everything out again it’s definitely worth it.

These are great filters! I change mine monthly, however, because I have two furry cats and one dog, and these really cut down on the fur and the dander in the air. That being said, they get dirty and filled up quicker than average in my opinion. But thats not problem, I just change the filter once a month when I receive my subscribe and save order and Im good to go! I havent had any issues with receiving a knockoff or incorrect product as other reviewers have stated and the price on Amazon cant be beat by any other store.
