Filtrete - 20" x 20" x 1" Allergen, Bacteria and Virus Smart Air Filter - White

Not only are these ridiculously expensive they are worthless. While they might filter, the false sense of connection makes them worse than a regular filter. The case of yet another big corp putting out stuff that simple doesn't work and charging an arm and a leg. Honestly I never want to buy another of even their regular products because if they lie about these they lie about them all. It's plain and simple fraud.

[This review was collected as part of a promotion.] I received this item as a free sample from 3M. My husband LOVED this technology. We change our filters often and this allowed us to not have to remember when we changed it last. The price was a bit steep, but a very awesome product

[This review was collected as part of a promotion.] Easy to use and replace my old filter. As I have found with all 3M products, good quality. Also, light and easy to store near my furnace. We have three animals and this helps cut the hair and dander considerably.

I purchased this product since I am horrible at remembering to change my filter. With the app available it tells me tips on how to have better air quality and healthier air quality ideas! I check it every so often just to see how much longer until it needs to be switched out. I will definitely be purchasing this brand everytime. Its also not a bad price with it having the technology it has.

When switching to being the one who wasn't responsible to buying the home filter to being someone who is, I wanted what I got to be worth my money. My wife and I live in a house with a smoker and since we are former smokers only once we quit did we notice the air quality needed some help. With these as our main home filter and a hepa purifier we are hardly ever sick anymore. It's nice to have the app to get a better idea of when we should be changing rather that guessing and never being sure if its to early or late. The bluetooth is so so but when you check being closer to it is when you're thinking about it anyway. [This review was collected as part of a promotion.]
