Filtrete 12x24x1 Air Filter, MPR 1500, MERV 12, Healthy Living Ultra-Allergen 3-Month Pleated 1-Inch Air Filters, 4 Filters

I have been very happy with these filters but ran into an issue this winter. At about 10 weeks it started restricting airflow to the point that the furnace shut down on over temperature. A new filter fixed the problem but I was mystified at first. I like them because they are sturdy and have a great rating for filtering small particles. I don’t know why it got restrictive before it was changed at the 3 month interval normally used.

Filtrete filters are not the cheapest alternative out there, but they are all I buy. Filtrete has filters with varying degrees of filtration and clear explanations of the difference in quality. If you just need to filter out dust and dont need to worry about allergens, the filter grade lets you choose the cheaper filter. On the other hand, if you do have to be concerned about allergens or bacteria and viruses, you can find the filter you need. The filtration levels are matched by price levels, but you know what you are getting. With many brands, you get a filter, but you do not really know the quality of the filter.

Little defect at corner, should still working. Amazon should really check their item before shipping, this is my second defect item sold by amazon. But I would still recommend Amazon over unknown providers as authentic 3M is the key for all. Shipping box is huge, so although theres a lot of bumps on the outside box, the products are still ok, not totally bend.

Although Filtrete products are more expensive than many competitors, the price is commensurate with the quality. Excellent fabrication and outstanding HVAC filtering. Prompt shipping with no product damage. Highly recommend.

I ordered 2 different sizes as thats what I needed. One size fit n place perfectly. The 12x24 did not fit well at all. I had to slightly bend, push and shove it into place. I dont understand why as I ordered the same before and the fit was perfect.

I needed to replace my furnace filter but didnt want to go out in the horrible winter weather. Ordered these and they are exactly as described. No complaints.

These filters fit as expected in our HVAC return air vent. There are arrows on the sides of the filter frame to show you which direction you should install the filter. The price from Amazon is fair for a two pack of MERV 12 filters, and doing Subscribe and Save helps keep me on schedule to replace the filters.

Excellent filters but I ordered wrong size. Had to return.

This grade of filter isnt for everyone but well worth if for allergy sufferers and pet owners. Your house will smell clean without sprays and air fresheners. You wont believe the amount of particles this grade of filter will remove from the air you breathe. Highly restrictive air flow so be careful on your first use. Condensation may occur on some furnaces. Excellent product!

Great deal on home filters for hvac too bad the corners were slightly caved in due to shipping damage.
