Filtrete MPR 1900 24 x 24 x 1 Healthy Living Ultimate Allergen Reduction AC Furnace Air Filter, Guaranteed Airflow up to 90 days, 6-Pack

Filters the air so well I can barely see it.

I could tell a difference right away! The dust is almost non existent in my house. I have two dogs and people with allergies comment all the time that my house is the only pet house where they barely get a reaction. I think its because these filters get a lot of the dander out of the air. Great product!!!

I have the same reservation as other viewers. Seems like a good filter (just tried so will update after some time), BUT there is NO marking indicating the actual MPR of these filters. Also, a web search using the code on the filter reveals that it should in fact be a Ultimate Allergen filter, but unclear if its the 1500 MPR, the 1700 MPR or the 1900 MPR? Would not order again from Amazon because of this.

These filters are a must compared to our old permanent filter that came with our heat pump. The micro filter removes 5-10 times as much dust and small particles as the old filter. This gives us peace of mind and less dust in the house to breathe. Although they are a little pricey, they are worth the money to improve our health.

These arrived quickly and work well. I like the idea of having a few extra without running to store for another.

Does whats its suppose to, I guess. Not sure how to evaluate the filters. Expensive.

A box full of filters on hand for those times when you forget three months is up, Where did the time go. Love the big box full.

I was advised by my furnace technician that while these more expensive filters remove more dirt and dust from the air, they restrict the air flow into the furnace, thereby making the furnace work harder. So its a catch 22. Cleaner air, your furnace works harder; or less clean air and your furnace will last longer. Not sure what to say about this. Techician recommeded using the cheap blue color filters that you can buy at Home Depot or other like stores.

best filter you can buy on the market and Ive tried them all due to my allergies. No need for hepa filters anymore! this filter catches everything that happens to pass by!

Been using these for years - will keep on using them - great quality for allergies! :)
