Save money

One PureAir 3000 is equivalent to 6-10 or more room air purifiers. Unlike other air purifiers where air must pass through the air cleaner to treat the air, PureAir purifiers emit the molecules needed to reduce microbes, V.O.C.s, wipe out allergens, mold and mildew spores.


Safer, Healthier Places to Live, Work, Learn, and Play

The Greentech PureAir 3000's 4 powerful air and surface purification technologies actively reduce tiny particles like viruses, bacteria, mold and mildew spores, V.O.C.s and other harmful microbes from your air. 

Other, passive type air purifiers require that the air pass through the unit to achieve any improvement in air. The PureAir 3000 emits the particles into your space, achieving a much greater level of purification.


PureAir 3000 Technology

The PureAir 3000 utilizes advanced technology to purify the air you breathe. In combining 4 technologies it will make the air in your home, office, RV, boat or any indoor space healthier. 

1. ARC  Photocatalytic Oxidation Cell 

This technology destroys bacteria and other harmful pathogens by breaking down the unsafe molecules leaving behind only carbon dioxide and water vapor. 

2. Needlepoint Ionization 

The PureAir 3000's advanced needlepoint ionization system creates negative ions that attract odour causing molecules, mold spores, dander, pathogens, allergens and dust. These particles clump together and drop to the floor, where your HVAC system can draw them in and filter them out.

Typical HEPA filtration units do not filter particles smaller than .3 microns. The PureAir 3000 can filter out even tiny nano-sized particles. This means less odour, mold, allergens, dander, bacteria and viruses and a healthier space.

3. Scalable Activated Oxygen (Ozone) Purification
Included but available without ozone on request.

Ozone is used by nature to purify and sanitize the air we breathe. The clean, fresh air we breathe after an electrical storm is the result of ozone being created as lightning passes through oxygen in the air.

The PureAir 3000 incorporates an ozone generator that can be set to run when you're not home or at the office, purifying the air naturally and safely. Ozone will revert back to regular (O2) oxygen quickly, leaving nothing but safe, clean, and sanitized air behind.

4. Electrostatic Filtration (HEPA Option Available)

The ionizing power of the PureAir 3000 will give the tiny particles in the air a little charge, this will cause them to attract towards each other and clump up. After the particles have clumped together into much larger particles, the electrostatic filter will easily remove them. This electrostatic filter is washable, making the PureAir 3000 much more affordable to use than air cleaners needing expensive replacement HEPA filters.

Great little purification unit!

In less than 24 hours, my entire lower level has a different smell...a CLEAN IONIZED AIR smell! I could literally tell the difference within a couple of hours in the room where I placed the GreenTech Environmental Whole House Purification unit, and then it just spread throughout the rest of the house, and now even my master bedroom on the opposite end of the house smells clean and purified! I have to admit, when it arrived and I unboxed it, I thought, "There's no way this small unit can do what they're advertising...", but it does! I initially started it on High mode with the setting at 1500 sq ft (roughly my lower level living space), and the fan on high. After about 12 hours, I changed it to mediuum speed on the fan, but kept it on High mode. This morning I dropped the fan speed to low but still on high mode as I need to keep it there to be able to adjust the sq. footage. Setup was incredibly easy. plug it in and it automatically starts running in normal mode. If that's what you want, then there's nothing else to do. I believe the high mode is for larger spaces or if you want to eliminate odors from cooking, etc. Instructions say to set it high up if possible, and away from your main home intake vent. I put mine in the formal dining room on top of the corner piece. It's out of the way, unobtrusive, and just quietly works in the background. I'm sitting in the family room through a couple of walls as I'm typing this and can smell the 'clean'. Highly recommend!

Compact and Quiet

It’s compact quiet and complete. It’s easy to setup and the control panel has an LED and pleasant back-lit control buttons. It also comes with a remote control and it’s own batteries. Operation is quiet enough to allow it to be operating 24/7, even on high fan speed I haven’t had it long enough to determine its air purification qualities, but according to the manufacturer the pureAir 3000 air purifier includes two technologies proven to kill mold, bacteria and viruses. These technologies are Photo Catalytic Oxidation (PCO) and activated oxygen or ozone (O3). Both technologies break down unwanted air pollutants at the molecular level. PCO has been verified to not only kill bacteria, virus and fungi (mold), but also to eliminate odors. It costs more than many other similar devices, but it’s rated to clean 3000 sq. ft., or the size of most full homes. Expectations are high, we’ll find out.

Great in my hair salon

I have had an air purifier in my hair salons for the last 12 years, and am especially pleased with your pureAir 3000 that has been in my salon for almost 2 years! Yours is much quieter, and seems to work much better than my old one, and it looks nicer, too. By having your air purifier in my salon, I know that not only am I much more protected from the normal pollution in indoor environments, but the added pollution of all the things that happen in the air in hair salons. I now have confidence that anyone that walks into my hair salon that is coughing or sneezing will most likely not pass it on to me. (There are exceptions, but I’ve only experienced those twice in the last 2 years!) I’ve actually had several of my return clients tell me that they just seem to breathe easier when they come in to get their hair done! It’s nice to know that I don’t have to breathe all those dead skin cells, pieces of hair, chemicals from perms or color, hair sprays, other people’s sick stuff and anything else that is in the hair salon air that would harm my health, anymore! And I’m also protecting my customers’ health. I loved the fresh air so much I got one for our home, and we got one for each of our children for their homes to protect them, too! I now sleep soundly (my husband says I don’t snore much at all now), probably because I don’t have to sleep with my mouth open now that I can breathe through my nose.

My son's allergies are way better

We bought the PureAir 3000 about a month ago because my son has developed allergies that were keeping him up at night. After running the air purifier for a few days we noticed he was sleeping though the night better. The sneezing and the watery eyes have gone away. Love that one unit covers our whole house

Wow! I can’t thank you enough

Wow! I can’t thank you enough for helping me with this purifier. My girls and I have been sick for months and I have done everything I can think of to try and get us better but with no avail. In less than 24 hours after getting this machine we have not been coughing and blowing our noses from the start of the day! The 1st night we actually slept through the night without waking up once!!! That is amazing. I can’t tell you the last time I have not woken up at least 2-3 times in the night. In less than 24 hours this house smells better and we are actually all even feeling better then we have in months. I can’t thank you enough for providing us all with this amazing sickness killing machine.
