Customer Reviews
Great deal on bulk filters
I was looking for some 16x25x1 air filters and needed a few of them. I found FactoryDirectFilters and saw they had multi-pack savings, which was exactly what I needed to keep costs down. I ended up getting a 6-pack of MERV 8 filters. The price per filter was much better than what I'd find at my local hardware store, even with shipping. The filters arrived quickly, within four days, and were exactly as described. I think I saved a decent amount compared to buying them individually. It felt like a smart purchase, good value for the money, especially since I use these regularly. Definitely worth checking out if you're buying in quantity.
Love my new custom filters!
I needed custom size air filters for an old system and FactoryDirectFilters totally delivered! I ordered two 2-inch custom width filters and they fit perfectly, I was so worried they wouldn't. The process for ordering custom sizes was super easy on their site. My air is so much cleaner now. I will absolutely be ordering all my filters from here from now on!
Consistent performance, good value
This is my third time ordering 20x25x1 MERV 8 filters from FactoryDirectFilters. I keep coming back because their products are consistently good. The filters always arrive on time, usually within a week, and they're always well-packaged. I've tried other brands before, but these just seem to last longer and keep the dust down effectively. The subscription discount helps too, making it a no-brainer to reorder. I appreciate that I don't have to think about buying filters anymore, it's just handled. The quality hasn't dropped off since my first order, which is what you want to see.
Good quality, reasonable delivery
I ordered a 20x25x4 MERV 11 pleated air filter and a 16x20x1 MERV 8 filter for my home. The ordering process on their website was straightforward enough, I found what I needed without much trouble. Delivery took about five business days, which was within the timeframe stated. The filters arrived well-packaged, no damage at all. Installing them was simple, they fit perfectly into my HVAC units, which isn't always the case with online filter purchases. I noticed a slight improvement in air quality pretty quickly, especially with the MERV 11. Customer service wasn't needed, so I can't speak to that, but the overall experience was solid.

Anyone know how long shipping usually takes for these guys to the East Coast, specifically like, Philly?
Thinking of signing up for a subscription to get my filters regularly. Is the discount worth it, or should I just wait for a sale?
Hey, I need some weird size filters for my old furnace. Do they actually do custom sizes that are accurate, or is it more like 'close enough'?
Are these filters actually good quality? I usually buy from Home Depot or Amazon, never heard of Factory Direct Filters before. Don't want to get scammed.
Can I use a military discount AND a first-time buyer discount at the same time? Or is it one coupon per order?
