Whole-House Air Purifier Installation in Larkspur, CO

A whole-house air purifier installs in the return air ductwork of your HVAC system, between the return ducts and the air handler or furnace. As your HVAC system pulls air from each room through the return grilles, that air passes through the purifier before being conditioned and distributed back through the supply ducts. Within a few hours of operation, the entire air volume of your home cycles through the purifier multiple times, dramatically reducing concentrations of airborne contaminants.

Different purifier types use different technologies to remove pollutants:

Media Filters (MERV 13-16)

High-efficiency pleated media filters trap particulates as air passes through. The MERV (Minimum Efficiency Reporting Value) rating indicates filter effectiveness, MERV 8 is typical for builder-grade systems, MERV 11-13 is good for allergen control, MERV 16 captures very fine particulates including most wildfire smoke. Higher MERV requires more powerful blowers or larger filter areas. Aprilaire, Honeywell, and Carrier all offer excellent media filter systems.

Electronic Air Cleaners (EAC)

Electronic air cleaners use electrical charges to attract and trap particulates on collector plates. Trane CleanEffects is a leading example. EACs can achieve very high efficiency on small particles but require periodic plate cleaning rather than filter replacement.

Polarized Media (Ionic)

Polarized media filters use weak electrical fields to enhance the filtering capability of replaceable media, combining the efficiency benefits of electronic systems with the simplicity of replaceable filters.

Photocatalytic Oxidation (PCO/RGF)

PCO systems use UV light and a catalyst to produce hydroxyl radicals that break down VOCs, odors, and biological contaminants. RGF REME HALO and similar systems are popular for homes dealing with cooking odors, pet odors, mold, and biological contamination beyond what filtration alone can address.

Activated Carbon

Activated carbon filters absorb gaseous contaminants, VOCs, odors, smoke odor, that media filters do not capture. Often combined with media filtration in hybrid systems for complete air treatment.

The right air purifier depends on your specific air quality concerns. MSI's free consultation covers each:

Primary Concern: Wildfire Smoke

Wildfire smoke is dominated by PM2.5 ultrafine particulates (less than 2.5 micrometers in diameter) plus a gaseous component. Effective wildfire smoke filtration requires MERV 16 or true HEPA media filtration paired with activated carbon for the gaseous component. Carrier Infinity Air Purifier and Aprilaire 5000 are particularly effective combinations.

Primary Concern: Allergies

Pollen particles range from 10-100 microns and are easily captured by MERV 11-13 filtration. For severe allergy sufferers, MERV 16 or HEPA delivers maximum capture rates. Pet dander and dust mite allergens fall in the same range. UV light at the indoor coil prevents biological growth that can release additional allergens into the airstream.

Primary Concern: Asthma

Asthma triggers vary by individual but typically include particulates, biological contaminants (mold, bacteria), and chemical irritants (VOCs). A comprehensive system with high-MERV or HEPA filtration plus UV plus activated carbon addresses all three categories. The American Lung Association recommends MERV 13 minimum for households with asthma.

Primary Concern: Cooking and Pet Odors

Odors are dominated by gaseous compounds that filtration alone does not capture. PCO systems like RGF REME HALO or activated carbon filtration are the right choices. These can be added alongside particulate filtration for complete air treatment.

Primary Concern: Biological Contamination (Mold, Bacteria, Viruses)

UV germicidal light combined with high-MERV filtration is the proven approach. UV deactivates biological contaminants in the airstream and on coil surfaces; filtration removes the deactivated material. See our UV germicidal light installation page for more.

Step 1: Free in-home consultation. We discuss your specific air quality concerns, evaluate your existing HVAC system and ductwork, measure static pressure to ensure adequate airflow, and identify the best installation location.

Step 2: System recommendation. Based on your concerns and HVAC compatibility, we recommend one or two specific purifier systems at different price/effectiveness points. We explain the trade-offs honestly.

Step 3: Written estimate. Itemized estimate covering equipment, installation labor, electrical work (if needed), filter replacement schedule, and any duct modifications required.

Step 4: Installation. Typical whole-house air purifier installations complete in 2-4 hours. Larger systems with significant duct modifications may take a full day.

Step 5: Verification and walkthrough. System tested for proper operation, airflow verified, and complete walkthrough of operation, filter replacement, and ongoing maintenance.

How much does a whole-house air purifier cost in Larkspur, CO?

Pricing varies by technology: media filter systems typically run $800-$2,500 installed; electronic air cleaners run $1,200-$2,800; PCO systems like RGF run $800-$1,500; complete combination systems (media + UV + carbon) run $2,000-$3,500+. MSI provides written estimates after the in-home consultation.

Will an air purifier reduce my allergy symptoms?

For most allergy sufferers, yes, sometimes dramatically. Effective particulate filtration removes most of the pollen, dust, dander, and mold spores that drive symptoms. Combined with regular filter changes and good housekeeping habits, many homeowners report significant symptom reduction within weeks of installation.

Will the purifier handle wildfire smoke?

With the right system, yes. MERV 16 or HEPA filtration captures wildfire smoke particulates effectively. Activated carbon addresses the gaseous component. The result will not be zero indoor smoke during severe events, but indoor air quality typically improves dramatically, often by 80-95 percent versus outdoor levels.

Does the air purifier need to run all the time?

The purifier operates whenever your HVAC blower runs. To maximize air cleaning during smoke or allergen events, set your thermostat fan to "On" rather than "Auto" so the blower runs continuously. The modest electric cost is far outweighed by improved air quality.

Will adding a high-MERV filter restrict airflow and damage my HVAC?

If installed correctly, no. The key is matching filter MERV to your HVAC system's static pressure capability. Some older systems with marginal blowers struggle with MERV 13+ standard 1-inch filters but easily handle the same MERV rating with deeper 4-5 inch media cabinets. MSI measures static pressure during the consultation and recommends only systems your HVAC can handle.

How often do I replace the filter?

Standard 1-inch high-MERV filters typically need replacement every 1-3 months. Deep 4-5 inch media filters typically last 6-12 months. Premium media cabinets (Aprilaire, Carrier Infinity) often go a full year. PCO and UV components have their own annual or bi-annual maintenance schedules. MSI offers filter replacement programs that handle this automatically.
