PuriFiLabs

This purification unit installs into residential or commercial HVAC system air ducts and uses a combination of sophisticated in-room sensors and a patented natural ionization process. The unit responds on-demand to properly maintain ideal indoor air quality 24/7, much the same way as a thermostat manages temperature. Revolutionary air and surface purification technology cause particles to clump together and become large enough to fall out of the air. The PuriFi unit targets/destroys the structure of bacteria and viruses. According to recent lab testing the PuriFi shows effectiveness in the elimination of 99.9% of airborne coronavirus test surrogates.

PuriFiLabs

Monitor and control your indoor air quality with a whole home solution that proves its results! When particulate levels are too high the PuriFi PM Sensor activates the patented PuriFi Generator. The Generator, which is installed in your central HVAC system, uses our patented process to begin sending an overabundance of natural oxygen ions through all of your air ducts. Our patented blend of high energy, oxygen ions flood every room and begin the purification process. Every register in your home or business becomes an air and surface purification system.

  • Natural ion generating air purification
  • Oxidizes tested viruses, bacteria, and household germs*
  • Reduces airborne particulates such as PM1, PM2.5, and PM10*
  • Patented PuriFi O2 Catalyst reduces unwanted ozone*
  • Reduced particulate levels are proven with in-room PuriFi laser particle counters
  • 5-Year Limited Warranty


Global Plasma Systems (GPS)

The GPS technology uses the ventilation system to transport a high concentration of positive and negative ions. Global Plasma Solutions create an indoor environment free of ozone and other harmful by-products. Patented needlepoint bipolar ionization (NPBI) technology disrupts the surface proteins on pathogens including mold, bacteria, and viruses, to render them inactive. These ions attach to particles suspended in the air, such as dander, pollen, dust, smoke, and odors, causing them to cluster together and become more easily captured through filtration. GPS further tackles chemical, cooking, pet and other odors to promote fresher, better-smelling air.

Global Plasma Systems

The patented needlepoint bipolar ionization or NPBI® technology, we deliver clean indoor air — producing neither ozone nor other harmful byproducts. NPBI technology safely creates and releases ions into the airstream using your existing HVAC system as the delivery method.

  • Natural ion generating air purification
  • Proven by 3rd party testing to inactivate 99.4% of SARS-CoV-2 viral particles within 30 minutes

PremierOne PureFlo HP500 System and PremierOne Multivoltage UV Germicidal Air Purifier with Odor Control

The PremierOne PureFlo HP500 System uses an advanced pull and push design. The motor draws the air through a pleated pre-filter to trap larger particles and uses a 300 cfm blower to create high pressure and force it through the HEPA media filter. The process is ultra-quiet, achieves a peak performance rating without constant maintenance, and with zero pressure drop, won’t hinder the operation of the heating/cooling system. While standard HVAC filters collect some bigger particles, submicronic contaminants pass right through. The PremierOne PureFlo polarized media air cleaner acts as a negatively charged allergen collection cell, capturing up to 97% of particulate at 0.3 microns.

PremierOne Multivoltage UV Germicidal Air Purifier with Odor Control

The PremierOne Multivoltage UV Germicidal Air Purifier controls germs, viruses and fungi using the powerful germicidal twin-tube H lamp that outputs more than three time more microwatts than single tube lamps. Patented odor control chamber can be easily adjusted by the homeowner to control odors and VOCs!

  • Auto-sensing ballast works from 120 VAC to 240 VAC
  • 180 Microwatts (16” lamp) 140 Microwatts (12” lamp)
  • 12” or 16” UV lamps available for correct fit
  • Lifetime warranty (2 years on lamps)

What our clients are saying

J. Jacobs

The service personnel were top-notch – friendly, professional, and dealt with some unexpected issues without missing a beat! Plus, they were dog lovers and made friends with my best buddy Highly recommended!

R. Larson

Extremely happy with my decision to use DNI. Installed cash price of my new furnace & AC unit was about 23% lower than the competition. Chris was very knowledgeable, conscientious, and top notch! The whole crew was excellent!

K. Kitten

Trustworthy, fair and will advocate for their clients. Whether it is maintenance or replacement DNI is wonderful. As a small business, the options are limited and expensive for replacing a unit that is original to the building. Chris L. worked exceptionally hard to ensure that our needs were met, ultimately finding the most cost effective solution.

R. Barcklow

DNI and Chris specifically were amazing. My furnace went out with the first Colorado storm and they were able to come out the next day and provided me with honest, transparent service so I could make the best decision for my budget. There was never any pressure from Chris between buying a new furnace and fixing my old one. I felt like they were patient and willing to work with me and my needs. I would highly recommend DNI for heating services.

D. Johnson

This crew has saved me on multiple occasions. From heating to ac service they have done it all for me. Always great customer service and a quick response time! Thanks for the continued great service DNI!

M. Southworth

DNI Heating got out to my house, assessed the problem and installed a new furnace for us within hours on a Friday afternoon. We did not have to worry about the 0 degree temperatures coming in that weekend. The service was great from the minute I called to helping us register our furnace.
