4 Pack FLT4825 Filter B Replacement with Activated Carbon Pre-Filters Compatible with Guardian HEPA Air Purifier AC4825 AC4825E AC4300 AC4800 AC4880 AC4900 AC4850

Great filters. Work like original ones. Very good quality...good price.

It fit the specified filter and works well.

Not only do I like the air purifier it goes in, but the replacement filters couldn't be easier to install. You can clearly see in the picture the before/after and the fact they are good quality and look good/fit well. This filter has helped regarding my allergies in a new environment to make the air in the rooms much less filled with partials and dander. They do not have a smell, so it gives me reassurance they are clean.

The machine itself is relatively quiet. I bought replacement filters from this seller. It arrived on time and was reasonably priced. The filter is a must because I have pets. These filters capture a lot of dust because I put them near litter boxes and areas where the pets hangout. I am told by people who come to visit they didn't realize I had pets. So good for me for keeping the areas clean and good for this filter for reducing allergens and pet smells.

They work well and last weeks. The cost is low for the quality.

These filters seem to trap as much airborne material as the filters from original manufacturer for a much lower cost. I have PM 2.5 / PM 10 laser particulate meter in the room and the readings have remained low when I use these filters. The look and dimensions of these filters is the same as the original. The fit is correct. The number of pleats for total surface area is the same as the original. The next time I need filters I will definitely consider this brand again.

These work, great. They are a wonderful replacement. A must have for all year round. They collect up so much dust that would be settling on the surface of things if not for these filters.

These replacement filters fit my Guardian purifier without any trouble. Installation was simple, and the filters sat snugly with no gaps or loose edges. The HEPA part does a solid job catching dust and allergens, while the carbon pre-filters help with everyday odors from cooking and pets. After swapping them in, I noticed the air smelled fresher within a day. The quality feels sturdy, and with two in the pack, it’s convenient to have a spare on hand for the next change. They make maintaining the purifier easy and reliable.

Very easy to install. Thought I was getting one, but there were 4 in the pack. Nice surprise.

This Filter is for Our Air Purifier, which does a great job!
