Lennox Healthy Climate PureAir PCO – Air Purifier Review

Lennox Healthy Climate PureAir PCO. An in depth look and review of the Lennox PureAir Air Purifier with UV Lights and Photocatalytic Oxidation.

Recently I wrote two articles about installing a Lennox LRP16 Package Heat Pump on my home in Mesa, AZ. In the first article, I talked about why I ultimately chose to install a Lennox unit on my home to replace the existing Trane Package Heat Pump I had installed ten years prior. The second article was a more detailed review of the Lennox LRP16HP after it had been up and running for a few weeks.

This article is about a specific accessory made for the LRP16, the Healthy Climate PureAir PCO Accessory. PCO is short for Photocatalytic Oxidation, and the accessory is available as one of Lennox’s many IAQ (Indoor Air Quality) solutions.

In order to maintain good indoor air quality aka “clean air”, you have to incorporate two processes; air filtration and air purification. The Healthy Climate PureAir PCO is responsible for the latter, purification. It is designed to be used with MERV 11 filtration which I’ll save for another article as this article is focused solely on air purification.

Clean air is healthy air, and healthy indoor air is important to me as I have interstitial lung disease, caused by thirty years of crawling around in attics and crawlspaces. Unfortunately, my lungs were the filters in very contaminated environments for many years While indoor air quality has to be a top priority for anyone with lung disease, asthma, allergies, or other lung/breathing disorders – it really should be something everyone thinks about for themselves and the health of their family!

I won’t fill this article with quotes and statistics about contaminant levels in today’s homes, links to the American Lung Association, etc., as if you’re reading this article, you probably already know you need to clean the air in your home. So, let’s get down to the details about the Lennox Healthy Climate PureAir PCO and my review.

What is Photocatalytic Oxidation (PCO)?

PCO technology reduces levels of airborne volatile organic compounds (VOC’s), cooking odors, common household odors, pollen, mold spores, and airborne dust particles.

What is the Measured Effectiveness of the Lennox Healthy Climate PCO?

When tested in independent laboratory studies, the Lennox HC PureAir PCO was confirmed to have reduced Total Volatile Organic Compounds (TVOC) by 50% within the first 24-hours of operation.

What is Included with the Lennox Healthy Climate PCO?

The kit includes everything your HVAC Contractor needs to install the accessory in your Lennox LRP16. But, the major components that are important to you the homeowner are; 1) UVA Lights (Ultraviolet A), and 2) the PCO Catalyst.

Is There Any Maintenance Required?

Both the UVA bulb and the catalyst should be replaced annually under normal operating conditions.

What are the Results?

Keep in mind, I was running high-end filtration, as well as air purification in my home before I installed the Lennox LRP16 Package Heat Pump and the PureAir PCO, however…since I waited a few weeks for the LRP16 to arrive (it wasn’t even available yet when I ordered it), I hadn’t been cleaning the air for a few weeks.

That said, I live in a nearby city of Phoenix, AZ where we have A LOT of airborne dust. It was also Spring and I live near orange groves so there is plenty of pollen in the air. Because of my lung disease, I very much notice when there are a lot of contaminants in the air, and I can say without a doubt that after one day of running the PCO, there was a noticeable difference. After a week, the air is clean and crisp!

My wife, doesn’t suffer from any breathing disorders however seems to have an acute sense of smell and always knows when I’m guilty of something if you know what I mean! While the Lennox Healthy Climate can’t cover up my odor crimes, it does do a good job of eliminating cooking odors quickly.

This week we fried sausages and onions one evening, and fish another. The house is buttoned up tight as a drum and the air conditioner is running all day because it’s 90 plus degrees outside. Normally, without the air purifier running those odors would linger all night and you would still smell them in the morning. Within a few hours neither of us could smell anything thanks to the Lennox HC-PCO

Bottom Line:

The Lennox Healthy Climate PCO gets the thumbs-up, and is a worthwhile investment for anyone considering adding it to a Lennox Package Heat Pump or Gas-Pack.
