Review
Dust Free (DF) Active air purifier is a filterless air purifier that uses the germicidal UV lamp to kill viruses, bacteria, remove mold spores and odors from the indoor air. It has no filters and the only part that requires a replacement is its UV-C lamps that has at least 2 year lifespan.
When it comes to the air filtration, there is no doubt that this machine kills viruses and bacteria. UV-C lamps have been used for decades to sanitize air in hospitals and other institutions that require the air to be as clean as possible. This technology is a number one when it comes to destroying various harmful particles and microorganism floating all around.
This air purifier uses ozone-free oxidizers and a negative ionization system to remove various microorganisms and VOCs from the air. It has no filter system that’s why it’s called an active system. This system is completely safe for use in both homes and commercial or public spaces.
The air purifier is installed into the HVAC system of your house.

The major difference between the Dust Free Active and Reme Halo is tonnage, weight and ozone emission. Dust Free Active is lighter and is designed for 3+ ton systems (12″ model) without producing ozone (doesn’t exceed 0.005 PPM during UL 867 tests).
On the other hand, Reme Halo is more powerful, cheaper and can be installed free of cost. However, it does release ozone. You can check my experience with the air purifier here.
Maintenance Costs
DF Active air purifier will increase your power consumption by a few bucks per year. The lamp requires a replacement ever 2 years in a worse case scenario, while the unit will work for years.
Pros & Cons

Wrapping Up
If you are living in a polluted area in a city, close to highway or simply to breathe clean air free of any smells then this is quite a good pick. Obviously, zero ozone emissions make it suitable to use at homes or other spaces without worrying about possible negative effects.
When it comes to downsides, there are initial costs that include price of one unit and installation costs. When it comes to operating one unit, there are almost none.

I purchased this unit two years ago. Once the first bulb burned out, the unit did not appear to be working after a new bulb was installed. The unit has stopped producing ozone. We used to smell the ozone for the first year or so. Now, we don’t believe the core is working. The person who installed the unit came by to check it and tried to convince me that he could smell the ozone as soon as he walked into my house. At that point, I felt like I was dealing with a used car salesman. Does the core produce the ozone? My wife and I are convinced that this unit is not working properly.
