Air Purifiers

Electronic air cleaners use an electrical field to trap and filter up to 98% of the pollutants traveling through your heating and cooling system. Among the best air cleaners for homes, electronic air cleaner systems are an advanced, easy-to-use and whole-house solution for dirt, allergens and other indoor air contaminants.

Modern media air cleaners trap and filter airborne particles more effectively and efficiently than in the past. Whole-house media air cleaner systems use replaceable filters to remove contaminants from air in your HVAC system. If you choose a media air cleaner system, an expert from HSP will tell you how often to replace your furnace filter.

Ultraviolet (UV) light systems kill up to 87 percent of certain airborne bacteria passing through your heating and cooling system. While in-home ultraviolet air purifiers are helpful for killing mold, bacteria and microscopic organisms, they do not filter particles from the air - they enhance your existing air cleaner system but do not replace it.


Whole-house humidifiers add moisture to your home's air as it travels through your heating and cooling system. Whole-home humidifier systems are installed in your HVAC system. If you experience itchy skin, dry throat, or static shock during the heating season, you may want to consider adding a home humidifier system.

Adding moisture to indoor air may also help reduce the spread of airborne viruses. Dry air allows aerosols to remain in the air longer, increasing the chance of human exposure. Moisture puts the aerosols into droplets that fall to surfaces, reducing the chance for inhalation.


Carbon monoxide alarms are an important part of any home, as 430 people die from accidental carbon monoxide (CO) poisoning each year, on average. HSP offers some of the best CO alarms on the market.
