germguardian Guardian Technologies FLT4010 Genuine High-Performance Allergen Air Purifier Replacement Filter A With Activated Charcoal Layer for Germguardian Purifier Ac4010, Ac4020 & More, Grey

The real deal! Great filter!

Fit perfectly and quick shipping.

We use the guardian tabletop purifier in my daughter's room to help with her allergies. After originally buying the air purifier at a retail store and getting an extra filter there I was happy to find this here on Amazon. It helps save a little money since they are less expensive and I don't have to make a trip to the store just to find it isn't in stock (only one store carries the filters near us and it's in a different town - and it costs more). Since we have to replace this every few months buying it here is a great option. It's really easy to change out and you can even see all the particles it catches when you take it out - so you definitely know it's working. Actually, when you walk in her room it smells different than the rest of our bedrooms so I can tell its working. For our needs this filter and air purifier works great and is rather economical compared to others that our offered in stores and here on Amazon. You can even add to subscribe & save and pay even less and that way you know it's time to change your filter when it arrives at your door. I don't think it can get much better than that!

i have been using them for a about a year now and i have definitely seen a difference in the quality of air in my home. for the first month or so i did not notice a change until the power went out, once that happened i was sneezing and my room didn't feel as fresh. if you are someone with lots of dust in your home (like if you can see dust particles floating around if the sunlight comes in) it will definitely clear things up. If however you are looking to have your home 100% dust free and want absolutely nothing in the air then you may want to invest in a higher quality air purifier. the other thing that is great about this is the price point, i spend 80$ a year but i'm almost never congested or sneezing at home. i have sleep apnea so congestion is an important factor for me especially. all in all a good filter and it delivered as expected too.

I used this filter to replace an existing dirty filter. Easy to replace and unit works great.

swapped these out after a 6 month period and wow was I supprised by the difference in the appearance BTW i actually have two if the one for my desk at home and one for desk at the office. I had purchased replacements in advance so I would be sure to have them when the time came and was glad I could replace both of them at the same time, I am going to try another 6 month replacement cycle and if the they both come out as dirty may drop it down to every 90 days, here is my hint, whiny buy your replacements in a permanent marker write on the box when it should be put in.message to the marketing / stocking / merchandiser PLEASE consider lowering the price point. There are great filter but IMHO they should be NOT more expensive than a 24 X 24 X ! filter that I use in my home

I get these in auto delivery every 6 months for.my small.bedroom air purifier. When I remove it, it has dust on it, so it must be working the way I want it to.

Works great for filtering dust and germs. Didn't know which side was out until I looked at the picture!

Quality

These work really well. They are the same price as big box stores except with Amazon, we have the benefit of home delivery.

works great. Rather then change is every six months, I vacuum it every three months and replace it every year.

just like it says, happy :-)

Prevents colds & countless other sickness's; why wouldn't you buy it?
