With two heavy shedding canines in the house along with the dust that magically appears daily, these filters a must in our house. They really trap an amazing amount of "stuff" which helps to clean the air in our house.

'These seem to be working well this summer. I bought them as a trial from 2800 after the HVAC tech suggested an easier way for the air to flow. So far I really can’t tell a difference except it’s better on my cash flow.

Filters Are great. We have 3 cats that adopted us and a lab my son adopted to us and these filters handle the hair and dander just fine . Not to mention they’re better value than the merv 11 I was gettin online.

Great product. It does what it says it's supposed to do. I change them every 3 months. I had my furnace looked up and they said it's one of the cleanest they've seen in a long time.

I purchased the Filtrete 90 day filters while an instant value and received a one year supply for $6 off the regular price. I trust these filters to keep my furnace and A/C operating at good performance.

I love these filters. I can feel very confident knowing that all pollutants and contaminants are being filtered out. The added bonus I wasn't expecting was having less dust in my home.

Fair price and high filtration. We change the filter at the start of every new season so four will last one year. They are well made and indeed do the job.

I have just changed the filter so I can't say anything about the filter yet. I did have directions that were easy to follow. I had no difficulty installing the filter

Been using these for 3.5 years now and they are doing a great job plus when you buy them at Sam's on sale, that even a better thing cause it's a great deal!!

Great Filters to use, our service guy said we could go up to 3 months before changing them out with good filters. We change them every 4 - 6 weeks but knowing we could go longer using a good filter is good to know.
