[This review was collected as part of a promotion.] Changed this filter exactly 30 days ago. WOW! Amazing quality air filter. Keeps my home's air fresh and clean. 5 stars.

I've used this particular filter since before I replaced my heat pump more than 18 years ago. And I must say that I'm fully satisfied with this product. I'm a retired HVAC/r technician What got me turned on to this product was when I was working with the local government more than 25 years ago when this was not available to the local public. Now I Will admit there's been times that I've gone more than 3 months whereas I would clean (brush off the dander and whatnot) to the life of the filter. Still, this filter preformed like a champ. I do my by-yearly inspection and for all this time my air handler doesn't show its age.

Easy to install and great image quality

just a great filter...i live alone and am extremely clean, and this filter still gets dirty, dirty, dirty. i never buy anything else...filtrete is my favorite. the photo is a shot of my friend who had just finished working on cars all day. as you can see my filter is as dirty as his hands. :)

We have a small home, but I have mold allergies and my husband has seasonal allergies. Plus, we have a small dog who is extremely furry and likes to leave that fur all over the house! We installed a new air conditioning unit when we moved in 5 years ago and have been religious about changing the filters with Purple Filtrete Ultra Allergen filters every three months and they are dirty as anything, but they keep the conditioner running smoothly and the air clean and breathable for us and the pup!

I have purchased several different micro-particle rating 3M filters and determined that the 1900 is the best all around filter for our needs. I operate the air conditioning & furnace fan on continuous service (low speed) so our two story house has reduced temperature variations per each floor. Since I operate the ventilation system non-stop, I will usually replace the filter about every 7 to 8 weeks, based on the airflow differential pressure (static) information provided at the thermostat. I have noticed after using the 1900 series filters that we have less dust particles on surfaces and in the air. When you visually compare 3M filter products to their competitor filter products you can immediately recognize that the 3M filters are of much higher quality. After using 3M filters for a while, you will notice an improvement in your indoor air quality.

I did not know how much was passing the filter I used prior to using the Filterete 1" Best filter, until I installed this filter and saw how much was on the filter when used for the same conditions, and for the same period of time. Now I use nothing else!

OUTSTANDING! ULTIMATE ALLERGEN FILTERS. I HAVE 4 DOGS THAT CREATE A GREAT AMOUNT OF DOG DANDER. THEY ALSO DRAG IN MUD THAT GETS CRUSHED INTO DUST. NO OTHER FILTER COMPARES TO THE 1900

I have a return this camera in April 17. They told me to wait for two weeks to get my money back until now. I have seen my money back. I don't know what's going on. I need to talk to somebody and I need my money back.

Too small buttons. Not easy to use
