GermGuardian EV9LBL Replacement UV-C Bulb and Filter Combo Pack for EV9102 Air Sanitizer
Given that the particular model this was made for is obsolete, I was very happy to find this at a much reduced price on germguardianoutlet.com. We are sold on Germ Guardian products. They have proven to be very reliable and stand up to the test of time. We will probably purchase a couple more just so that we have them -- I am guessing that they may not be on the market much longer.

It however worked just fine.

Makes me feel fresh knowing it is inside the machine killing the bad stuff.

The single biggest design flaw for Pure Guardian's 7.4 L output per day Ultrasonic Humidifier Tower is that water must be put in at the bottom, and then the tank inserted just exactly right on the base. If not, water can spill on the surrounding ground.

It will produce a nice, steady steam and humid cloud over hours and can last several days on a tank, if used correctly. The display at the top can be a bit hard to read, especially in darker conditions.

I have three dogs and I have this set up in a small bedroom next to their beds. It smelled like plastic when I first plugged it in, but after 24 hours of running the room it’s in smells like nothing! The room doesn’t smell like dog or like a air freshener trying to cover up dog smell, it just smells like nothing!

Overall I’m very happy with this product!

This is used by the spouse to eliminate dust particles and odors in the home
We've noticed quite the difference in our breathing
Thanks to the people for inventing this !!

I am very happy with it so far. I thought top filling would be easier and it is so much easier that I run it much more than my Levoit because I don't have to take it to the sink to fill and then carry the very heavy full tank back and after about 5 or 6 tries finally get it set right - no more of that ! It is super quiet and with the light on it's easy to see if it's getting low. I use tap water that I run through my Brita filter and there is no white dust. The warm setting is as warm as my Levoit ( which is not very warm ) It also doesn't have a setting for the humidity that turns off but the one on the Levoit went wacky so they replaced it and the new one has also gone wacky. As far as how often and hard it is to clean I can't say as I've only had it for 2 weeks.
