[This review was collected as part of a promotion.] We were admittedly overdue to change our filter and noticed an almost IMMEDIATE difference in the air. I had been waking up with headaches recently, which have since stopped, and I attribute to allergens that had been coming through the vents from our old filters. We are extremely happy with these filters so far!

[This review was collected as part of a promotion.] This is just a furnace filter. But it's really good quality and fit perfectly into my furnace cabinet. I'm not sure how I'll be able to know it works well other than waiting for a month or two to pass and understand if it works. I would think if it shows up dirty then it works!

[This review was collected as part of a promotion.] I suffer from allergies so I thought I would give these a try. I'm so glad I did because these work great. Since we started using these filters my allergy symptoms have lessened. I would recommend these if you suffer from allergies like me.

[This review was collected as part of a promotion.] This is a very nice filter screen. Appears to be high quality and has a nice thick feel to it. It is not a cheap flimsy filter like some products. Seems to be doing a nice job in the house as well. It was easy to insert into the furnace too.

[This review was collected as part of a promotion.] I can’t say enough good about this filter. Since using it I’ve noticed a difference in my allergies and quality of air. I feel like I can breathe better and don’t wake up congested as I usually do. I know it’s working for my air purifiers that I keep running throughout my house show that my air quality has improved. These are definitely my new go to filter going forward. I definitely recommend!

Good filter's and the price was great.

These are usually around $20 each anywhere else. These were 4 for $40 or &10 each

Great product at a very consumer price!

Filters are fine. The “pickup” experience was awful.

Glad to see them, not on list buy on last filter.
