GOODVAC Replacement HEPA Filter Compatible with Filter Queen Defender 4000 HEPA Air Purifier

Is nice to find replacement filters at a reasonable price. I have 3 Defender air cleaners in my home so I shop for the best price because I simply can't afford the Filter Queen brand anymore.

Because of several fires in our area this year and numerous air alerts issued by the Health Dept, a replacement filter was desperately needed for my air purifier. The business I originally purchased the filter from went out of business; was so thankful to find a source for the filter. It arrived in mint condition, fit perfectly and was easy to install. My Filter Queen Defender is again working and keeping the house smoke free.

I stopped using my defender in 2008 when I could no longer pay the $300 for this filter and the charcoal wraps. In 2006, the dealer actually billed my credit card for two filters and I was told that they would not refund the money, I had to take the extra filter. When I needed a new filter, I stopped using the unit, Now I find the exact same thing on Amazon for less than a third the price. This is why I use Amazon. I can get what I need at an excellent price delivered to my door. Thank you Amazon!

Once again I was shopping around the net to see where I could get the best deal at. The filters were delivered quickly, in good condition and were as advertised as far as quality. They were also well packaged to protect them during shipping. They fit perfectly which I've had problems with in the past, even when purchasing locally. I keep ending up at Amazon for so many purchases...

easy to change the filter and reset the red flashing light on my air purifier.

so far it is doing its job and the price was very fair. The manufacturer wanted $100.00 for a replacement as I recall and thats just a rip-off. I would recommend this product. I did compare it to the old one, and I don't see any major differences, but it is a filter so the eye may not see the difference. But I'm satisfied as the air in my house is still being filtered.

I own 2 Defender HEPA filtration units and this is the 2nd filter I have bought from this company. Buying these replacement filters just make sense. They work/fit perfectly. And it saves me a bundle not having to buy direct from the sales rep. I highly recommend this product and will continue to purchase all my filters from here.

Not the same product I was used to getting from the company, but it is as described by seller. I am using it and so far it is working as well as the original. I bought it to save money as it is cheaper than the original. Good deal for the price.

Thanks for the amazing filter, we are truly enjoying it.

Expensive filters, but works great
