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

Good for what they are -- cannot find a higher MERV for sale on Amazon.

good for the price

Great!

These filters are the very best. Dont have to dust so often. They are less expensive than permanent filters and work better.

I like it as it is the best that I can find in a narrow filter - to lower dust and allergen content in my house.

Really happy with this purchase, it saved me time and money, how can you lose. I buy these filters anyway, and there is only one store around here that sell this size. Thanks!

Very nice

These are excellent filters, but very expensive. Bought with gold box deal which made it worthwhile. I would buy again.

5 out of 5

I have been using this very filter on my heater, which may be older than the 3M company which makes them (well, a bit of an exaggeration). So, that is about as good a testimonial I can give on the quality of the filters. What I really like is the price of this six pack. It seems pricy at $100, but in the home improvement mega marts, they may cost over $25 apiece. On line, a similar pack of 6 averages between $110 and $130. Since I regularly shop at Amazon, buying them here gives me added incentive because it will add to my bonus points. For a pack which will last for three seasons, I cannot be more satisfied with this product and order.
