Good filtration

Costco is significantly cheaper if you have a membership. I have been using MPR 1500 filter for years. it. Very efficient filter but had to change in 3 months. It provides very good filtration and dust inside home is reduced quite a bit. I can feel it is really improve the air quality by removing allergens, pet dander, odours & dust. If you don’t mind paying more these are very good filters.
