Whole-House Air Purifier Systems

Posted by phoenixrises @phoenixrises, Tue, Sep 17 1:43pm

Has anyone found a safe whole-house air purifier system that is installed in (or around) your in-home HVAC system? My HVAC company recommended the Reme HALO whole-house in-duct air purifier by RGF, but I was concerned to learn it’s an “ionized hydro-peroxide” output that includes some level of ozone being emitted into the air from what I read in their literature/site and from talking to the manufacturer. They say it’s “safe” but I’ve read people with lung problems shouldn’t breathe in any ozone (I have Bronchiectasis). I also couldn’t get a straight answer as to whether the UV light is part of the Reme HALO or a separate UV bulb that shines on the AC coil (called the BLU QR UV stick light) or whether both have a UV component. I’ve read that UV in whole-house air purifiers (and whole-house water systems) is safe for humans – I’m more concerned about whole-house air purifiers that emit ozone. I’m also looking at whole-house UV purifiers without ozone (e.g., APCO-X, Purity, Field Controls Trio). All of these products are hard to decipher. I live in a townhouse with a small space for the HVAC system. I have 2 small Winex air purifier floor units (from Costco) that I use but I’ve learned that isn’t enough to remove harmful mycobacteria and mold spewing into the air from the HVAC air ducts and the AC coil where moisture builds up. If you have knowledge and experience about these systems, I’d appreciate your thoughts!

@phoenixrises– Welcome to Connect. My husband and I installed. We have a couple of different models. They have to be designed for your house by a reputable company. We use https://www.carjon.com/. We have a Heat exchanger, Split System Heat pump with hepa filters. I have animals and it really helps with that and other nasties around the house. Since we had this installed for my lung cancer stage IV a couple of years ago I have no problem breathing or humidity. I am not familiar with MAC or other bacteria in the lungs. But check it out, maybe it will help. Will you tell me more about your illness? What treatments have you had for it?

@phoenixrises – Hello. Have you come to any decisions regarding you in home purifying system?

@merpreb, Hi, we haven't decided on a whole-house air purifying system as yet. We know we don't want one that is an ionizer, hydrogen-peroxide, or plasma-based because they emit some degree of ozone. Some UV-based air purifying systems produce ozone; some don't (if the bulb is coated?) – so I'm still researching this. Also, the UV-based system seems to need 2 units – one with filters and UV and a separate UV light for the coil. Some research questions the effectiveness of using the UV-based system, even if it doesn't produce ozone. The more I research, the more complicated it's becoming and more red flags (where you install it is also important, the wavelengths, etc.). I'm not sure if there is actually a whole-house air purifying system on the market that doesn't have caveats for people with lung issues and that actually will purify the air of bacteria (including NTM), viruses, mold, etc. It has to be very strong to do that and possibly the heat/AC fan has to run continuously(?), which I don't want. So, I continue to research on this topic. I'm surprised more people haven't joined in the conversation!

We have a Honeywell electronic air cleaner system with UV light. It does produce a wee bit of ionize but has never caused me any problem. I have 1 and 1/3 lungs due to lung cancer in 2015. I was treated three years for MAC. I also have Bronchiectasis, Emphysema, Asthma, and allergies. The air cleaner has been a godsend.
