I love Guardian Tech's air purifier

I love Guardian Tech's air purifier. With replaced filter, now I can breath the clean air again in my room. The only downside of Guardian's product is the noise.

You can see the difference!

I've had my germ guardian air purifier for almost a year now. I have changed the carbon pre filters several times to extend the life of the hepa filter. You can see the difference in the filter over a year of being well maintaianed and vacuumed out ever so often.. it works!

Excellent HEPA filtration for a highly allergic person

I replace these HEPA Filters every 3 months and you know when it is time to change them when the leaving air side of the filter turns dark from entrapped dirt when it starts out white. The pre-Filter should be washed w/ Hand Soap and Water, dried and reapplied. I also take the HEPA filter part outside and throw the intake Air section down on my cement walkway to knock out loose dust to give it longer life. Really nice filter and best I’ve used at a reasonable cost to replace. I’m very familiar with HEPA & MERV rated Filters from working Commercial and Industrial HVAC, and these have little to no leak through and have high velocity air circulation when loaded, which is very good to see in a filter of any kind.

These are great! Clean, fresh smell

This product works great! I turn it on before bed and feel like we get fresh air all night. Helps with allergies if (like in other reviews) you replace this every so often. I switch mine after 4-6 months having a dog & two cats.

I really find this filter helps in my home. ...

I really find this filter helps in my home. The only thing I can say is the companies idea these last over six months is insane. We don't smoke but have pets and this needs changing every 80-90 days. They are dark grey and cause the unit to run much louder by 90 days of use.

AC4100 identical replacement filters

Purchased this "E" style replacement filter pack for our Germ Guardian AC4100 (the little one that looks more like a speaker). Have had the air purifier for just about a year, but officially only has about 5 months of use on it. Both filters were quite dirty, so figured it was time to replace them. As far as I can tell, this was the genuine filter set for our purifier. Visually the same as the old filters (minus all the nasty filth), and fit into the purifier exactly the same. Have had the new filters in for half a day and can notice a positive change in the smell in the room, and the purifier seems to be running just a little quieter. Old filters may have had a little restriction, or I may just be imagining things.

High quality product. Wish it was a 2 pack though- too expensive.

Expensive but seems to be a quality product. Happy with purchase, not happy with price. Though I’m aware of many good filters being sold expensively. Still doesn’t feel worth it but I needed it so... I wish I got 2 in the pack. Definitely would justify the price then.

Nothing can stand up to my dog room

It works really well, but nothing can last as long as I like because I have dogs, but it catches a lot and makes my room feel a lot cleaner. I have to change these about every month to a month and a half

Easy to replace filter

Best simple to understand, little but powerful air purifier with a very easy to replace filter. I love it and I am about to buy my second unit. I have it for a year and a half and only now changing out the filter for the first time. I have just vacuumed it in the past...And rinsed the attached sponge off.

Good filter, gets rid of odors, easy to install, best for small rooms

Helps with general stale or musty odors from rooms that don't get a lot of ventilation. I can sleep with the lowest setting on, it kind of acts like a white noise machine. I bought the machine and just switch out the filter every several months. Works great.
