Cleans the air throughout your home – even while you’re away

Unlike passive filters that affect only air that passes through them, pureAir 3000 projects purifying solutions to the sources of pollution inside your home, continuously removing odors and airborne particles. Set your desired level of cleaning for while you are home or run a deep clean while you are away and come home to pure freshness!

Neutralizes tough odors

Using advanced technologies including our proprietary form of photocatalytic oxidation, active radiant catalysis (ARC®), activated oxygen (ozone), and ionization, pureAir 3000 significantly reduces odors caused by bacteria, mold and mildew, as well as eliminating other odors, including those from pets, cooking, and smoking.

Reduce allergens from your breathing space

Negative ions are projected out into your space, causing harmful particulates including pet dander, pollen, and other allergens to clump together until they fall out of the breathing space and can be swept up or caught in your HVAC filter.

Easy to set up, easy to use

With easy setup, use, and maintenance, improving the air quality of your indoor environment is a breeze. pureAir 3000 does not require frequent air filter replacements. Regular cleanings and only once-per-year part replacement will make it simple and affordable to keep your home fresh.

    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. 🙂

  2. Liz B

    Thank you GreenTech Environmental for creating such an exceptional air purifier! Our church nursery is germ and virus free for our little ones!

  3. Scott

    I recently purchased a pureAir 3000 Air Purifier for my home and I couldn’t be happier. I have two young children who are at home most of the day and were constantly getting sick or had some sort of cough. Since getting our unit and properly breaking in our house I have noticed a significant difference in my children’s health. They haven’t gotten sick or had any sort of cough. It helps me sleep better at night knowing your system is taking harmful elements out of the air in my house. I really appreciate your product and your wonderful sales staff and would recommend this to others.

  4. Kim

    We have 3 cats in our home. Our daughter and her 3 children often visit us and used to complain that their allergies bothered them when they were here. However, now that we have the air purifier they don’t seem to have barely the problem. Also, when our daughter brings her two dogs (that don’t seem to affect their allergies) there was always a doggie smell in the house when they left. Now with the air purifier that smell isn’t there. Our kitchen leads into the family room and cooking odors such as fish, used to linger in both rooms, but with the air purifier ruining the smells quickly go away! We are very pleased and we’re very happy we purchased it and would recommend them for anyone to use in their home.

  5. Sara & Jeff T

    We’ve been using our pureAir 300 for a while now. In that time, we’ve noticed a drastic decrease in sickness in our house, increased air ‘freshness’, and a feeling of confidence knowing that harmful bacteria and mold are kept at bay. Kudos on this fantastic machine.

  6. Elizabeth P

    I was on a Christian re-treat for a few days. This retreat was held in several parts of a closed church that has recently been rebuilt. Most of our meetings were in what was called the old church that was several years old. On the first day of the retreat several of the members were complaining of eyes burning, itchy throat, and coughing. We finally discovered that there was most certainly mold in the old church building. So I thought to myself hummmm I think I know of something that might be able to help us get through this weekend! I set up a few pureAir 3000’s around the church and a pureAir 1500 in the main room that we would be occupying throughout the weekend. It took a matter of about an hour to clear the air and made everyone so happy to feel like they could breathe again!!! Everyone was so thankful to have fresh air and no more itchy eyes and coughing!

  7. Joey G

    I’ve owned tons of air purifiers both of the ionic type and just regular hepa filter types. None even come close to the pureAir 3000! This product is built to last, aesthetically pleasing and simple to use. I’m a Chiropractic student in Georgia right now and currently live in an 800sqft apartment and with our philosophy of health and wellbeing this product is a perfect match! I remember going to my Aunt’s house years ago and she had a similar unit in her home. I would always wonder why it smelled so FRESH and CLEAN in her home. Now I realize she had a similar product that cleans NO purifies the air completely. The smell is that of that unmistakable fresh smell just after a thunderstorm is the best way I can describe it. I’ve also been suffering with chronic dry itchy and red eyes and after only 3 days of running the pureAir 3000 those symptoms are completely gone! Unbelievable, that chronic allergy problem was getting on my last nerve and I gladly would’ve paid $1000 to get rid of it. When I have company come over they walk in and I can see them immediately take a huge whiff of air and sigh and say what is that amazingly fresh smell? And of course then we have a discussion about the pureAir 3000 and they are amazed that this small little unit on top of my fridge is responsible.

  8. Theisen

    We purchased our air purification unit in late January and I can’t say enough about it. We are in an old building and it had a constant musty smell. We used a dehumidifier and candles to combat this musty smell. These things helped but needed to be run constantly to be effective. When we did the trial with the air purification unit I told myself that I would be happy with a 50% improvement, I did anything short of knocking the building down and starting over would help with the musty smell. I was shocked and delighted that within less than a week the musty odor was completely gone!

  9. Susan E

    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. Our kids love theirs, too. I think everyone (businesses and homes) should have a pureAir 3000 to protect themselves, their employees, clients, families, friends, and even their pets from indoor air pollution.

  10. Mike W

    We have a pureAir 3000 and a pureAir 50. We have inside cats; after we purchased the product we have noticed a big difference in the air. We love the product!

  11. Elizabeth C

    My Mother-in-Law is very allergic to cats, so it makes it hard for her to come visit us and see her grandchild while she is in town. With the help of the pureAir 3000 she can come visit and even stay the night with the cat in the house and have no issues at all!

  12. Mary Ann P

    The pureAir 3000 is a fantastic product! When my friends come in they always comment on how good my home smells. When I am cooking something with a strong, unpleasant smell-I turn the air purifier to away mode and the smell is gone within a few minutes. I love this product!

  13. Linnie R

    I use my pureAir 3000 to keep the air in my home fresh and healthy, but the most impressive use for my pureAir 3000 is to remove odors from vacant houses that I buy to remodel and resale.

  14. Hilary E

    I am asthmatic and the pureAir 3000 unit has helped me so much. My children also have severe seasonal allergies, and it has helped give them some relief. I don’t know how we lived without our unit; it is one of the best health investments we’ve ever made.

  15. Ruth R

    I have two purification units, one for a large area and one that is more focused and smaller. I also have 4 house cats. I couldn’t live in my house without the purifiers. I recommend purifiers to anyone that wants a clean smelling house and pure air!

  16. Crystal G

    I am a smoker. I love my air purifier. Even though I smoke my house doesn’t not smell like smoke because of the pureAir 3000. It makes the air smell clean along with my house. I would recommend anyone get one, even if you are not a smoker like me. I t is easy to use and cleaning the unit is easy, and the benefits of it are amazing.

  17. Tony & Nora

    Our air purifier is an ongoing part of our ‘healthy choices plan’. As a business owner, facing the public in any state of their medical status, we feel the purifier is one more means of not only protecting ourselves, but our customers as well! Thank you for servicing us! You are doing a great thing for those you care so much about!

  18. Inga H

    I have been a friend and customer for over 25 years. I like the pureAir 50, 250, 500, & the pureAir 3000. They produce ozone air; the house always smells fresh. It takes 15 watts to run the unit with no hepa filter (which can be quite expensive). The cleaners always help to eliminate infection and bacteria. Thank you again for wonderful products!

  19. Carolyn M

    When we first plugged in our pureAir 3000, I was a little bothered by the ozone smell, but not everyone in the family even noticed it. Guess I was just a little sensitive to it. My son came home to visit and mentioned that it smelled like mountain air, not what he would expect to smell in a house. I have since become accustomed to it, though I can still notice it some. One of the biggest things I have noticed was that although we did still get some sinus colds over the winter, the mucus never turned color and the colds did not last long. Did so much better this winter and now with the spring pollens does not seem bothered at all.

  20. Dr Ed & Sherry

    We purchased the pureAir 3000 about 6 months ago for our Chiropractic office. My nose was constantly dripping while at work and now it doesn’t! We highly recommend this product!

  21. Pay H

    My allergies have improved tremendously since using the air purifier. I also have 2 cats and it helps with dander and odor!

  22. Rosella H

    I love it! The air is cleaner and smells wonderful!!! Thank you for better indoor air!

  23. Mike M

    Our church purchased 2 of the pureAir 3000 units to clean the air in our old repurposed building. Originally built as an auto dealership, the building has lots of old toxic smells buried deep into the thick concrete walls. The lower level also had mold issues from the flooding. The units have worked well in eliminating those smells, and have also helped keeping the air purified during cold and flu season. The units were a great investment for our church. Thank you!

  24. Beth M

    I purchased a pureAir 3000 unit to clean the air at my parents 100+ year old home. The air was very stale and full of dust and other environmental toxins. Later the walls and ceilings were painted and hardwood floors were refinished. I relied on the pureAir 3000 tp clean the air of those fumes. The unit worked so well, I use it in my own home now. Thank you!

  25. Eric C

    In the past, walking into our print shop it smelled like offset press ink and cleaning solutions. Now with the GreenTech pureAir 3000 installed our print shop smells like clean fresh air! We’ve very pleased with the pureAir 3000 and the ability to control the fan and air purification levels to get the right setting for our shop.

  26. David N

    The money I invested in my pureAir 3000 has been worth every penny. The ability of this machine to eliminate odors is truly fantastic! I would highly recommend this product to anyone!

  27. TracieM

    We are in Oregon where there are fires surrounding us and on level 1 evacuation warning for days. Others are on level 2 which means be ready, and level 3 which means get out. We are suffering heavy smoke from all the fires, and there is nowhere to go, everywhere there are fires and smoke. We pulled out our PureAir cleaner and it has been running non stop since the fires started bringing smoke in. It’s helping significantly. Outside has been hazy, yellow and orange skies. We are not taping windows and doors, just running PureAir. The air quality here has been between 300 to above 500, so it’s not safe to breathe outside. PureAir is definitely saving us. I bought it 3 years ago after a house fire. Not because of the fire, but because we moved into a rental house with mold exposure. After 6 weeks, we found we were exposed to mold, and got out before we could get our belongings out. The landlord allowed mold abatement in the house with all our belongings still inside. I’m unfortunately allergic to mold and mold spores. Long story, but had to move into new rental with belongings that cross contaminated into new rental and was sick for a couple months with everything I had with mold spores on it. I consulted a professional who introduced PureAir and life began to get better quickly. I had to isolate everything into one space, and treat it, then vacuum the mold spores off after they were dead from being treated in area using PureAir. If you’re allergic to mold spores such as I am, you might still be affected until they are completely gone/removed. This was a lot of work, but PureAir was awesome with taking care of cleaning the air and killing the mold spores. I went from being SICK to completely better in about 10 days. I had lots of help with cleaning items from my husband, and this took months. We were so surprised how fast I got better once we got this and kept it running. It is absolutely worth every penny!!! We also put a bunch of things out in the garage and put it on away mode to kill mold, worked great! When we returned home after the fire, we have used it from time to time to help with allergies when pollen has been bad. But with the storm and all the fires across state of Oregon like we have never seen before, we are so thankful to have had this ready to go! We just bought a smaller unit for our daughter in college so she can use it for her allergies and possibly with the smoke as well. If you are on the fence, this unit has been amazing!!! I can also vouch that it certainly does work for a substantial area-4000sq ft rental house and now 2000sq ft house.

  28. GreenTech Environmental

    Thanks for letting us know!! We’re so happy to hear you are feeling better… and helping your daughter breathe easier in college! Please stay safe and remember to clean your filters for optimal performance!

  29. N-Aleem J

    I don’t even know where to begin! My partner and I purchased the PureAir 3000 whole-home system originally because we noticed our 6-month old Dalmatian was beginning to develop some serious allergies. We do a deep cleaning of the whole house once a month and weekly vacuuming etc. already, so we figured the issue had to be with the air quality inside; especially considering we’re both working from home due to COVID-19. So, we ordered the system and it arrived on Sunday. We saw a review that stated to let the unit run on PCO for 24 hrs prior to starting the full purification setting. We followed that and then after the 24hrs turned the purification setting on to 250sqft (our home is approx. 2,858sqft) adjusting the setting by 250sqft approx. every 12 hours until we had the unit set to the square footage of the house we’d like purified (2,250sqft excluding our basement). Results we’re astounding we honestly notice a difference in the first 20-30mins honestly. The air was refreshing and light almost like after a big rainstorm and everything is cool and calm outside, fresh! The first night when we reached 1000sqft for the setting we noticed Argos had stopped scratching significantly and even I, with my own set of allergies, noticed I had no sinus irritations or random night coughs! We notice it eliminates a lot of odors and keeps everything smelling fresh. Even the blackened salmon from last night’s dinner was quickly wafted away. No need for expensive plugins anymore! Truly pleased with the unit and looking forward to a fresh, clean, and airy future. Important Note: When set to the max. sq. ft. of your home ensure all doors to the rooms are open. For the unit to be effective, if portions of the home are closed adjust so the system is only purifying for the accessible areas (i.e. we have set to 2,250 less the basement which we don’t use often at all). Also, we have a split HVAC for each floor of the home. The unit is closest to the air return to the first floor (largest sqft area of our home) It still does amazingly well with purifying upstairs regardless! Would also advise elevating the unit a bit and having a damn good vacuum! You will notice major dust in the first few days (the technology doesn’t work like traditional air-pull purifiers …read more on the website) but after a good vacuum and dusting kiss the constant dusting and vacuuming goodbye! (this I’m truly excited about).
