Tio2 Treated HEPA Filter Replacement Compatible with Electrolux Aerus Lux Guardian Air Cleaner Purifier, High-efficiency HEPA Filter, 2 Pack

The filter fit perfectly and seems to be functioning as well as the Aerus original item.

Great seller 😁

This filter is great quality and fits well in the Guardian Air

I was impressed and I was long overdue to change mine. Well worth it

Half the price of the originals. Good quality. Fits perfectly in my unit.

I have changed my mind.By carefully opening the opposite side of the machine, I was able to fit this filter into my Aerus Beyond Air model F159E.This delights me to no end!Before this, I was convinced I had ordered a filter that did not fit, and I started a Return. But during the next day, I suddenly had the thought that perhaps I was being an idiot, and that I should reconsider how to get the filter inside the machine.This is how decisions are made.I have canceled my return.

So far so good, but I just installed the filter. Since my air purifier is older my concern was sizing, well it fits like it is supposed to.

Well made, quality materials as the original one
