Neena 12 days ago

I change the air filters every 3 months and discount filters is my supplier. They shipped their quality products quickly and accurately. This time when I ordered the wrong filter dimensions, the lady I was talking with pointed out that I needed a different size. She saved me from ordering the wrong thing! The filters work great and are much better priced than the equivalent ones available locally.

Product is of quality materials and does the job.

Robert Jones 19 days ago

They definitely fit correctly. They usually last about two months. I do a lot of woodworking in the basement and it can get dusty in the same room where the furnace is. I’ve blocked off the slot in the return where the filter slides in with a magnetic sheet and I think that helps. I like having six delivered at once so I don’t have to run out looking for the best deal at Lowe’s or Home Depot.

braulust 20 days ago

I like these filters. They have a MERV rating of 11. I tend to use filters with a MERV rating from 8 to 12. These have a solid rating and are well priced. I change filters every 3 months which my HVAC service company recommends. I purchase these in a case of 6 for an even better discount and I dont need to order for 18 months.

Good quality filters but there has been a substantial increase in the cost over the last 18 months. Ordered ahead to avoid further increases. Only buy when there is a big discount from your list price otherwise, would look for other options. Have been buying for several years now and also for my Mothers heating/AC system.

Happy shopper 24 days ago

These are really good filters. I like being able to buy them online. I keep the box of filters in the attic then when it’s time to change filters in the a/c I just get one out of the box. They come 6 in a box so they last a long time.

This is the 2nd time I ordered these filters and they arrived quickly and are quality filters at a great price. I buy these instead of waiting for sales at the big box stores.

Glad I found them and will continue to buy their best in brand products.

Weather is fine quality-wise but does not quite fit the furnace. I don't think the correct size is available. The thickness of the filter is a little bit too much and I had to trim it in order to get it on to the furnace. Otherwise, everything seems fine.

Its amazing how many particles this filter pulls from the air each month when I change it. My air conditioner is now over 15 years old and I believe it’s due to changing the filter every month.

Madeleine Fabris 18 days ago

Haven't used on yet, however, they are the same as what I've been using that I paid over $12.00 at a store. With ordering 6 at a time (change my filter ver month) they cost around $6.00 each. Huge savings, and always have one on hand.
