Whole House Air Purification in Puyallup

Clean indoor air is a cornerstone of a healthy home, especially in Puyallup, where seasonal smoke, persistent humidity, and year-round pollen can degrade indoor air quality. Whole house air purification systems treat the air throughout your forced air system to reduce particulates, microbes, odors, and volatile organic compounds (VOCs).

Why Whole House Air Purification Matters in Puyallup

Puyallup’s Pacific Northwest climate poses unique indoor air challenges:

• Seasonal pollen: Spring and summer trees and grasses trigger allergies and asthma
• High indoor humidity: Promotes dust mites and mold growth in winter and spring
• Wildfire smoke: Late summer smoke brings fine particulate matter indoors
• Older homes & leaky ducts: Allow outdoor pollutants and soil gases to enter
• Household activities: Paints, cleaning products, and building materials emit VOCs

Whole house air purification treats air centrally, ensuring every room benefits—without the noise, maintenance, or limited coverage of portable units.

Common Whole House Air Purification Types

True HEPA Filtration

• Function: Captures airborne particles down to 0.3 microns (pollen, dust, mold spores, pet dander, and wildfire smoke particulate when combined with prefiltration).
• Installation: Downstream of HVAC blower or in dedicated air handler. Requires sizing or blower modifications due to higher pressure drop.
• Best for: Allergy relief, particulate removal, smoke events

Ultraviolet Germicidal Irradiation (UVGI)

• Function: Uses UV-C light to inactivate bacteria, viruses, and mold spores; prevents mold buildup on coils and drain pans.
• Installation: Near coils or inside ductwork.
• Best for: Microbial control, HVAC efficiency, supplemental pathogen reduction

Photocatalytic Oxidation (PCO)

• Function: Oxidizes organic compounds into simpler molecules (CO₂ and water vapor) to reduce VOCs and odors.
• Considerations: Effectiveness depends on contact time, catalyst surface area, and VOC types; modern systems minimize byproducts.
• Best for: Household odors and VOC reduction (combined with activated carbon)

Bipolar Ionization / Cold Plasma

• Function: Produces charged ions that attach to particles and microbes, causing them to agglomerate or become easier to capture; some units also inactivate microbes.
• Considerations: Performance varies; some devices can produce ozone if not engineered properly. Choose independently tested systems.
• Best for: Particle agglomeration and supplemental microbial control

Activated Carbon and Sorbent Filters

• Function: Adsorbs gases and VOCs, including smoke odor and household solvents.
• Installation: Media section in air handler or dedicated cartridges.
• Best for: Odor and VOC control, smoke mitigation

How Purification Supplements Filtration and Ventilation

Filtration: Captures particulates; HEPA or high-MERV filters remove fine particles. Purification technologies enhance this by inactivating microbes.

Ventilation: Balanced ventilation (HRV/ERV) exchanges stale indoor air with fresh air without excessive heat loss. During wildfire smoke, ventilation can be reduced while recirculating and purifying indoor air.

Integrated approach: Combine source control, filtration, activated carbon, germicidal methods, and ventilation. Greenhead Heating evaluates homes to recommend the right mix for Puyallup conditions.

Installation Considerations

• System compatibility: HEPA or dense media may need blower or duct adjustments; UV and PCO require electrical access.
• Home volume & airflow: Size units to home volume and HVAC CFM for adequate air changes and clean air delivery rate (CADR).
• Ductwork condition: Seal and insulate ducts to improve distribution and prevent outdoor smoke or soil gases from entering.
• Placement & zoning: Central returns and main ducts affect purification speed; multi-zone homes may need supplemental units.
• Control & verification: Integrate controls, sensors, particle counters, VOC meters, and CO₂ monitors to track performance.
• Electrical & safety: Ensure devices meet emission and safety standards; select independently tested products.
• Maintenance access: Filters, carbon cartridges, and UV lamps must be easy to access for routine upkeep.

Local considerations: Seasonal pollen, damp-weather mold risk, wildfire smoke, garages, and wood stoves may require enhanced source control and carbon filtration.

Performance Expectations

• Particulate removal & smoke: HEPA filtration significantly reduces airborne particles and visible dust.
• Microbial control: UVGI and ionization reduce microbial survival in airflow and inhibit coil/drain pan growth. Most effective as part of an integrated IAQ strategy.
• Odor & VOC reduction: Activated carbon/sorbents remove many household odors; PCO provides supplemental reduction. Staged treatment may be needed for persistent odors.
• Time to improvement: Particulates often decrease within hours; odors and VOCs may take longer depending on source and media capacity.

Limitations: Purification does not replace source control, ventilation, or moisture remediation for existing mold.

Maintenance & Verification

Routine maintenance:

• Prefilters: Inspect every 1–3 months; replace when dirty
• HEPA/High-efficiency filters: Replace every 12–36 months
• Activated carbon: Replace 6–12 months for higher load homes
• UV lamps: Replace annually or per manufacturer
• Ionization: Inspect/clean every 3–6 months
• HVAC coils/drain pans: Clean annually
• Duct inspection: Every 3–5 years or sooner

Verification testing:

• Baseline particle counts & VOC measurements before installation
• Post-installation testing of particles (0.3–10 microns), VOCs, and humidity
• Periodic audits for ongoing performance
• Biological sampling if microbial concerns exist

Documentation: Maintain logs of filter changes, lamp replacements, and testing results for long-term performance tracking.

Pairing Purification with Other IAQ Measures

• Humidity control: Maintain 40–60% RH with dehumidifiers or ERVs to limit dust mites and mold.
• Source control: Reduce VOCs, vent stoves/dryers, store chemicals outside living areas.
• Ventilation upgrades: HRV/ERV systems provide energy-efficient fresh air; switch to recirculation with purification during smoke events.
• Duct sealing & insulation: Prevent outdoor pollution and improve system effectiveness.
• Targeted solutions: Additional units in basements, garages, or pollutant-prone rooms.
• Smart controls & monitoring: Particle, VOC, and humidity sensors adjust purification and ventilation automatically.
