Customer Reviews
Good price, quick delivery
Needed new furnace filters. Ordered a MERV 11 filter, 20x25x1. Price was good, and it arrived in about 4 days. Fit perfectly. Easy transaction overall.
Consistent quality for fridge filters
I've been getting my refrigerator water filters here for a while now, probably my fourth or fifth order. This time I picked up two more under sink water filters. They're always reliable, fit my fridge perfectly, and the water tastes clean. Shipping is consistently fast too, usually within a week to my door. I stick with them because I know what I'm getting, and the price is always fair compared to what I'd pay elsewhere. No reason to look around when these work so well and arrive promptly every time.
Got my AC filters fast
So I totally forgot to get new AC filters before summer hit, classic me, right? Jumped on Discount Filters and grabbed a few pleated air filters. I think they were 16x20x1. I was kinda worried they'd take forever to get here, but nope, they showed up pretty quick, like 5 days to reach Denver. They fit my unit just fine and seemed pretty sturdy. The whole process was super easy, no fuss at all. Definitely saved me a trip to the big box store, which is always a win.
Decent filters, some shipping issues
I ordered a couple of refrigerator water filters for my Samsung. The filters themselves seem fine and worked well, and the price was definitely better than buying from the appliance store. Shipping took about a week, which was a bit longer than I hoped, and the box was a little dinged up when it arrived, though the filters were okay. Their customer service was helpful when I had a question about installation, but I wish shipping was a tad faster and more careful.
Discount Filters Community Discussion
Share tips, ask questions & help fellow shoppers save more
can you use more than one coupon code at checkout? got a first order discount but also saw a 10% off promo floating around.
Does anyone know how fast shipping usually is to, like, California? I need some new AC filters pretty quick before it gets super hot.
Anyone compared Discount Filters to FilterBuy? Trying to decide where to get my new furnace filters from.
What's their return policy like if I accidentally order the wrong size furnace filter? I always mess that up.
Hey, wondering if anyone knows if Discount Filters sells the actual name brand filters or just generics? My HVAC tech told me to stick with the Honeywell ones.
