FAQs
What is the difference between a whole-home air purifier and a portable room unit?
A whole-home air purifier is integrated into your existing heating and air-conditioning (HVAC) system, so every time the blower runs it treats the air in the entire living space. A portable purifier cleans the air only in the single room where it is placed. Whole-home units offer consistent filtration, quieter operation (because they live in the ductwork), no floor space usage, and only one set of filters to maintain. Portable units are useful for spot treatment but lack the coverage and convenience of a centralized solution.
How is a whole-home air purifier installed and will it work with my current HVAC equipment?
Most systems are installed in the return-air plenum (the duct that feeds air back into the furnace or air handler). The purifier cabinet simply replaces a short section of duct, so no major remodeling is required. Because it is installed in-line, it works every time your existing blower fan runs—whether you are heating, cooling, or just circulating air. In most cases, the purifier is compatible with furnaces, heat pumps, or air handlers of any brand. A professional technician will size the unit to your ductwork, ensure the pressure drop is within manufacturer specs, and wire any needed power or control connections.
What pollutants and particles does a whole-home air purifier remove?
Depending on the model chosen, whole-home purifiers can capture: • Dust, pollen, and pet dander (as small as 0.3 microns with true HEPA or high-MERV media) • Mold spores and certain bacteria • Smoke and combustion particles • Volatile organic compounds (VOCs) and odors when an activated-carbon stage is included • Some systems add UV-C or photocatalytic light to inactivate airborne viruses and microbes. By continuously cycling air through multiple filtration stages, they typically remove up to 99% of common indoor contaminants.
How much maintenance is required and how often do filters need to be changed?
Maintenance is straightforward. High-MERV media cartridges generally last 6–12 months, compared with 30–60 days for standard 1-inch furnace filters. True HEPA canisters often last 12–18 months, and carbon modules 6–12 months, depending on indoor air quality and run time. UV lamps—which do not block airflow—should be replaced every 12–24 months to maintain germicidal effectiveness. Your HVAC contractor will note the service schedule and can bundle filter replacements with routine heating and cooling tune-ups.
Will running a whole-home air purifier increase my energy bills?
Modern purifier cabinets are engineered for low pressure drop, so they have minimal impact on the blower’s workload. In many cases, upgrading to a 4- or 5-inch media purifier actually improves airflow compared with a clogged 1-inch filter. The system uses the HVAC fan you already operate for heating or cooling; any additional electricity is negligible. Some homeowners choose to run the fan in ‘circulate’ mode for continuous filtration—this adds only the cost of fan operation, which can be reduced by using an efficient variable-speed blower.
Can a whole-home air purifier help with allergies, asthma, and persistent household odors?
Yes. By removing fine particulates like pollen, dust mites, and mold spores, whole-home systems significantly reduce the triggers that aggravate allergies and asthma. HEPA-grade units capture up to 99.97% of particles down to 0.3 microns, while optional carbon stages adsorb cooking, pet, and smoke odors. Continuous filtration means irritants are caught before they settle on surfaces or are inhaled, leading to noticeably fresher, cleaner air and fewer respiratory flare-ups for sensitive occupants.
