Product Overview

The Guardian Air Desktop air purification system is the perfect fit for kitchens, pet areas, basements, nurseries or anywhere there are unwanted odors or other contaminants. The RGF Desktop is a freestanding product that can be plugged in to any 115 volt household circuit and can be moved from room to room. The unit goes right to work actively producing hydro peroxides that sanitizes and eliminates contaminants in the air. There are no moving parts in this product so it insures whisper quiet operation while working hard cleansing the air we breathe. The Guardian Air Desktop by RGF is designed to eliminate sick building syndrome risks by reducing odors, air pollutants, VOCs (chemical odors), smoke, mold spores, bacteria and viruses. The PHI Cell improves air quality in any indoor environment with fresh, clean, odor free air. Hydrogen peroxide is a naturally occurring element in our atmosphere that gives us that country clean smell. How does the RGF patented process work, our units have a broad spectrum UV (Ultra Violet) light that reacts off of rare catalytic metals on a surface surrounding the bulb. This reaction creates an Oxygen atom, which changes the molecule of water (humidity) from H2O to H2O2 which is Hydrogen Peroxide. This vaporized hydrogen peroxide wants to attach itself to any virus, bacteria, odor or mold spore which organically changes the contaminate, killing it. This is the perfect solution for indoor air quality (IAQ) for any room or office.

Customer Questions & Answers

How does the air from the entire room get filtered with no fan? It seems it would only clean the air close to it.

Asked by: jvv
You are correct. The chance that a negative ion makes it more than a few inches from the device before encountering a positive ion is VERY low. If you wear this on your head it might make you a little healthier.

low humidity

Does the process need a high humidity environment to be effective?
Asked by: mike
No, I am in Colorado, and there is not much in the way of humidity at all, and it works great.

Rated 5 out of 5 by from Air Purifier I have a reptile collection in a 400 sq ft basement with poor ventilation. Although the critters themselves don't smell, the subsequent excrement smell buildup presents a pretty bad odor. Imagine an indoor chicken coop with 10 chickens and no ventilation. I plugged in this product and within 2 hours the smell was greatly diminished. The next day the odor was barely noticeable. The next day I fed out 50 mice to the collection and in 2 more days the critters began to void. Previously, I would be hit in the face by the odor of snake urine and feces as soon as i started walking downstairs into the basement. This time I smelled nothing out of the ordinary even though there was snake excrement in every cage. This product is truly amazing in its ability to destroy odors. I highly recommend this product to pet owners worldwide!!!

Rated 5 out of 5 by from Surprised that it actually works! We had a UV light installed in our hvac system and had no noticeable difference, so when i bought this i wasn't expecting much. But with Home Depots great return policy I figured that i wasn't risking much. We have 7 dogs, cook fish daily and I'm extremely sensitive to smells. We were boiling vinagar and lemons and cinnamon and had a ton of plugins everywhere and still the fish smell would creep upstairs and make me ill. Since plugging it in haven't smelled fish once! The air feels different to breath in. Almost like its cold air mountain air which is a big difference considering its vegas. Only thing that worries me in how long till the uv light gos out. The unit is only covered for 90 days. Normally UV lights only last about a year and I don't see a way to replace it. So $200 a year per unit/room per year might not be the most cost effective.

Rated 1 out of 5 by from Don't bother It's supposed to neutralize the odor, but all it does it replace it with another, chemical odor that's just as repellant. Lot of money for nothing. And if it does work, you have to replace the bulb probably within a couple of years. Right now I could not find anyone, including home depot, who handles the bulb nor could I find a price on it. I returned this item

Rated 5 out of 5 by from Incredible fresh indoor air results This desk top air purifier worked wonders in my old office building where the windows don't open and the carpets are old. The room has a freshness that I know is now cleaned through this all natural process. I will be getting this for my home next!

Rated 5 out of 5 by from Clean Air Small unit but definitely works well. Not good for big rooms but definitely changes the composition of bad air and makes it very sterile ! All good.
