Got this to help filter out the smoke during the California fires. Trust only OEM filter to fit and perform great.

Reliable and excellent HEPA air filter for the air purifier by Germ Guardian! I love the filters and the air purifier

The hepa filter fits my air purifier perfectly and is working great. No issues that I can tell.

filter lasts a longtime and yes i wash it and reuse it multiple times.

I have allergies so a good air filter is a must. The Germ-Gaurdian is an excellent air filtration system for the money. Were I used to live a house burned down across the street from mine filling my home with the awful smoke and burned out house smell. I bought two of theses filters systems and in 12 hours they had completely cleared the air. Those two AG were on constantly and lasted 5 years. So when I moved I bought two more.

It was easy to install. Its working exceptionally well.

They last a long time, do a good job filtering and are fairly cheap to replace versus other air purifiers. Can’t complain.

I do notice a difference in the air quality/smell with this filter. I periodically remove it from my air filter to see the difference that it makes and it is outstanding. Definitely a need of you have pets or live in a high pollution zone.

Easy to use. Very effective. Great price. Ship quick. I have bought several for home & office

We bought a GermGuardian - AC4825DLX air purifier in January and have been very pleased with it. In fact I bought one for my son. We needed to change the filter after six months so I bought two replacement filters. I thought I would have to change the filter more frequently so I am pleased with how long these filters last.

This is a great air purifier system for small rooms. You will want the name brand here the knock offs on other sites aren’t as good.

Ordered the item from Best Buy and it got delivered in no time at all. Genuine part for my air purifier- easy to install and no problems whatsoever. No regrets with the purchase.

We’ve had our Germ Guardian for about two years and never changed the filter. YUCK! We didn’t use it consistently for two years, as it has been in storage for about 9 months and then only utilized once in awhile. When we changed the old filter, Good God was it gross! This new filter is making a huge difference now that we put it in my roommates bedroom at night to help with her allergies (seasonal and pet).

The filtering works fine, but I noticed that the frame of the replacement filter is angled compared to the one the unit came with. The original filter would happily stay in place with the plastic cover removed. The new one has an angle on it that it falls out as soon as the cover is removed and actually makes it harder to put back together because of this. It was so different that I had to compare the model number on the filter as well as double-check that this wasn't some generic knock-off. Very surprised by the quality change of the official filter. Things like this take away all incentive to pay for the more expensive name-brand filter.

Good filter i have a lot of pets and i can definitely tell when it needs to be changed so it makes a huge difference in the air quality

Being allergic to cats and still wanting to have a cat makes air filters a must. We have been using these filters for years and just bought two more updated versions and they make a huge difference. Especially if you vacuum them inbetween filter changes.

So far, so great. Installed the filter about a week ago. It has been working as intended as far as I can notice. Actually, maybe even a bit better than the filter that came with the original packaging for my Air Purifier. My only and biggest issue with this product is the PRICE. I think $40 is quite steep.

These are easy to install and fit our unit perfectly

This works well for my air purifier and lasts a while.

Original replacement filter for our Guardian Air Purifier which really helps during allergy season. It's a little pricey considering we purchased the air purifier at a discount. New filters definitely make a huge difference with the air quality.
