Air Purification Systems St Louis

St. Louis Air Purification Systems


Air Purification Systems St Louis. Everyone would love to come home to a fresh, clean, allergen and dust free home. Weis Comfort Systems understands this, and that is why we can install a new Air Purification system. With this new system, it can be achieved.

What is an Air Purifier?

Well, isn't air purification the same as Air Filtration? Somewhat, yes. The difference is that air filtration is mainly there to keep the inner working of your HVAC clean and running to the best of its efficiency. Although it does use the conventional filters, it only reduces the amount of dander, pollen, and airborne particulates in the air that is recirculated from your HVAC unit; It does not completely clean your house of all the bacteria and microbes that still will be in the air. These bacterias are are going to need a more in-depth cleaning.

An air purifier, on the other hand, cleans the air in indoor spaces by removing unwanted particulates. In fact, a high efficiency particulate air (HEPA) purification system can theoretically remove at least 99.97% of particles as small as .3 microns, according to the United States Environmental Protection Agency. Different air purifiers use slightly different technologies and are designed to target specific pollutants in the air. To help you choose the air purifier best suited for your needs, consider what is essential to you and your family.

iWave

What is iWave?

The iWave product family has recently proven its capabilities. This technology significantly reduces a wide variety of pathogens in breathable zones and non-porous surfaces. Weis Comfort Systems is proud to offer this air filtration system to our clients in the Metro St. Louis area.

iWave Air Purifiers

iWave Is Proven Effective At Removing COVID From The Air

Human Coronavirus 229E reduced by 90% after 60 minutes

This test was run using the iWave-C (GPS-DM48-AC) in a test designed to mimic ionization conditions like that of a commercial aircraft’s fuselage. Based on viral titrations, it was determined that at 10 minutes, 84.2% of the virus was inactivated. At 15 minutes, 92.6% of the virus was inactivated, and at 30 minutes, 99.4% of the virus was inactivated.

SARS-CoV-2 (Covid-19) reduced by 99.4% after 90 minutes

This test was run in a test chamber in a lab setting with the Nu-Calgon iWave-R Air Purifier P/N 4900-20. A petri dish containing a pathogen is placed underneath a laboratory hood, then monitored to assess the pathogen’s reactivity to Needle Point Bi-polar Ionization (NPBI) over time. This controlled environment allows for comparison across different types of pathogens.

The Latest Technology

Here at Weis comfort systems, we use the latest technology to help protect you and your family from allergens and pollutants of all kinds. Breathe easy AND rest easy knowing you have an iWave product installed by one of our talented technicians.

An iWave product, like the iWave-R, is a whole-home air purifier that installs inside any ducted HVAC system within a home and removes particles, smoke, odors, and allergens.

It uses a patented technology, called “needle-point bi-polar ionization,” to inject negative and positive ions into your air system in order to make contact with active mold spores, bacteria, or viruses. Once attached, the ions remove the hydrogen molecules, stripping them of the source of energy and causing them to die off.

Not only that, the ions also attach themselves to allergens such as dust, pet dander, pollen, and other particles so that when they band together, they become large enough to be caught in your home’s air filter — giving you the full spectrum of clean air.

With over 200,000 installations nationwide, the iWave line features air purifiers with many great features, including:

  • Kills viruses, mold, and bacteria
  • Actively purifies the air in your home
  • Maintenance-free and self-cleaning in most designs
  • Installs in any HVAC system
  • Non-stop protection
  • Proven bi-polar ionization technology
  • Limited warranty
  • Does not need costly replacement parts
  • Does not require yearly replacement bulbs or cells
  • Does not produce harmful byproducts

We want to help improve your overall air quality and protect you against common bacteria and viruses, like the novel Coronavirus. Don't hesitate to reach out to Weis Comfort Systems today to learn more about this cutting-edge technology or to have one installed in your home now!
