We’re not quite out of the woods yet as far DandelionInFieldas colder weather goes, but March is definitely the turning point when it comes to springtime. Now that February is behind us, you’re surely starting to eagerly anticipate the warmer weather and blooming vegetation that spring brings with it. Keep in mind, however, that spring can bring a number of problems with it as well. This is especially true for those of us with allergy and/or asthma symptoms.

Contrary to what some homeowners seem to believe, the air in our homes is not inherently of high quality. In fact, it is possible that the air in your home is more polluted than the air outdoors! If you want to breathe clean, healthful air in your home all year long, you may require professional indoor air quality products and services in Loveland, CO.

Dust, Dirt, Pollen, And Other Airborne Pollutants

Because you’ll be going in and out of your home more now that the weather is nice, and because there is more exposed dust and dirt outdoors in the spring and summer than there is in the winter, it is possible to track these pollutants into the house with you. Plus, blossoming vegetation means pollen that can go airborne outdoors and find its way into your home. The first line of defense against these airborne pollutants is an air filter.

The air filter in your HVAC system, unfortunately, is probably not going to cut it. These filters are of low efficiency, with a low MERV (minimum efficiency reporting value). Your system may be able to handle a more efficient standard filter, but using a designated filtration system that complies with your HVAC system is a better option. You may also opt to use an air cleaner, such as an electrostatic precipitator, to take a more active stand against these pollutants.

These electronic air cleaners feature ionization chambers that charge the pollutants in the air. Those pollutants are then trapped on collector plates that are oppositely charged. The plates can be removed by the homeowner for simple, convenient cleaning.

Biological Pollutants

Removing dust and dirt from the air is an effective way of dealing with such pollutants. However, not all pollutants can simply be removed from the air successfully. Living microorganisms, such as mold spores, viruses, and bacteria, are often too small for such an approach. They are also biological entities, meaning that they can reproduce. Destroying them and rendering them incapable of reproduction is really the only way to effectively deal with them.

Using UV air purifiers, like UV germicidal lights, will do the trick. Installed in your ductwork near the air handler, these lamps emit UV rays that disrupt such pollutants at a biological level. They are entirely safe for animals and people in the house. They should be used to supplement, but not replace, more traditional air filtration/purification systems, as they do not filter airborne pollutants out of the air.

Homeowners today realize that maintaining comfortable temperatures in their homes is really only part of the comfort equation. The other is maintaining great indoor air quality within their homes. This can be more difficult during the heating and cooling seasons, as opposed to the more mild spring and autumn months, due to the fact that we seal up our homes quite tightly in order to maximize efficiency. With the right IAQ products and services, though, you can still maintain a clean, healthy environment. Using the proper equipment is key, though. If you are up against biological pollutants, for instance, you really need to consider the use of UV air purifiers in Loveland, CO

When to Use UV Germicidal Lights

Not every home is going to require the use of UV germicidal lights. But those that do will benefit significantly from them. UV germicidal lights use small, safe amounts of ultraviolet radiation to destroy biological pollutants within ductwork. They are typically installed near the air handler, so as to treat all of the air passing through the system. Biological pollutants include viruses, bacteria, and mold spores. If you have issues with frequent illness in your home, or if mold keeps popping up, using UV germicidal lights is an option to consider.

Limitations of Use

Most residential HVAC systems cannot fully filter out biological pollutants, as the pollutants can continue to reproduce even once they’re trapped in the filter. That is why air purifiers that destroys pollutansts are so beneficial. Remember, however, that such systems won’t do anything to remove more run-of-the-mill contaminants from the air in your home, such as dust and dirt. That is why purifiers should be used in conjunction with more traditional air cleaning/filtration systems, and not be mistaken as a replacement for those options.

Air cleaners, both mechanical and electronic, can do a great deal for your indoor air quality. But when it comes to biological pollutants like bacteria, viruses, mold, mildew, algae and fungi, mechanical and/or electronic air cleaners may not be able to capture the biological particles you need them to. A great solution for not just removing, but eradicating, biological pollution is the installation of UV germicidal lights in your Loveland home.

What Are UV Germicidal Lights?

UV germicidal lights are lamps that emit UV-C rays. These types of rays destroy the DNA of biological particles, which not only kills the particles but destroys their ability to reproduce. So, unlike air cleaners, UV lights don’t capture biological pollutants: they destroy and eradicate them.

What Can UV Lights Do?

  • Stop mold and mildew growth inside your AC
  • Eliminate odors
  • Destroy VOCs (volatile organic compounds)
  • Generate negative hydroxyl ions, a natural compound that helps destroy pollution
  • Kill bacteria and viruses

The effectiveness of UV germicidal lights is virtually unmatched, as they kill over 99% of the pollutants that come into contact with the rays. They are easily installed and can be placed in a number of locations throughout your system, including the evaporator coils and the ductwork. The cost to run UV lights is minimal, about 1 cent per day.


UV lights do not filter anything; as such, they do not capture and remove particles like dust, dirt or pollen. This is why it is highly recommended that UV lights be paired with an air cleaner so that your air is both filtered and purified. In addition, micro-organisms must be within site of the UV rays in order to be affected.


UV lights last about a year, so it is recommended that they are changed every 12 months regardless of whether or not they are still working. They can also attract dust, so you may need to wipe them off every few months to maintain their effectiveness.

If you have concerns about biological pollutants affecting your health and indoor air quality, it may be time to consider the installation of UV germicidal lights in your Loveland home.
