Quick Answer
The 4 pillars of allergy-proofing: Control dust (vacuum 2-3x weekly with HEPA filter), protect bedding (allergen-proof covers, hot water washing), improve air quality (HEPA purifiers, fresh HVAC filters), and reduce humidity (30-50% prevents dust mites and mold).
San Diego's beautiful weather comes with a catch: our mild climate means plants release pollen nearly year-round. Add dust mites, pet dander, and mold to the mix, and allergy sufferers face challenges inside and out. The good news? Strategic cleaning can dramatically reduce indoor allergens.
The average home contains millions of dust mites, invisible to the naked eye but major allergy triggers. Their waste particles are what cause reactions, and these particles accumulate in bedding, upholstery, and carpet. Here's how to fight back.
Allergy Reduction by Area
Bedding
- Wash sheets weekly in hot water (130°F+)
- Use allergen-proof mattress and pillow covers
- Replace pillows every 1-2 years
- Deep clean mattress every 6 months
Flooring
- Vacuum 2-3x weekly with HEPA filter vacuum
- Use washable rugs instead of wall-to-wall carpet
- Mop hard floors weekly to capture settled allergens
- Consider removing carpet in bedrooms
Air Quality
- Change HVAC filters monthly
- Use HEPA air purifiers in bedrooms
- Maintain indoor humidity 30-50%
- Clean air ducts every 3-5 years
Surfaces
- Dust with damp microfiber cloths (dry dusting spreads allergens)
- Minimize fabric upholstery and drapes
- Clean blinds and shutters weekly
- Wipe down hard surfaces frequently
San Diego Allergy Challenges
Year-Round Pollen
Unlike regions with true winters, San Diego has overlapping pollen seasons. Trees (January-April), grass (April-June), weeds (August-November). Some residents experience symptoms year-round.
Santa Ana Winds
These dry, dusty winds blow pollen and allergens everywhere, including into your home. Keep windows closed during Santa Ana events and dust/vacuum after winds subside.
Coastal Humidity
Near the coast, humidity supports dust mite and mold growth. Use a dehumidifier to maintain 30-50% humidity. Bathroom exhaust fans are essential to prevent mold.

- HEPA vacuum cleaner (sealed system)
- HEPA air purifier for bedroom
- Allergen-proof mattress and pillow encasements

Frequently Asked Questions
When is allergy season in San Diego?
San Diego has multiple allergy seasons: tree pollen (January-April), grass pollen (April-June), and weed pollen (August-November). Many residents experience year-round allergies due to our mild climate allowing plants to pollinate throughout the year.
How often should I change HVAC filters if I have allergies?
Change standard filters monthly, or upgrade to HEPA or high-MERV filters (changed every 3 months). During high pollen periods or Santa Ana winds, check filters more frequently. A clogged filter can't trap allergens effectively.
Do air purifiers really help with allergies?
Yes, particularly HEPA air purifiers which remove 99.97% of particles 0.3 microns and larger, including pollen, dust mites, and pet dander. Place one in your bedroom for best results—you spend 8 hours there nightly.
Should I keep windows open or closed for allergies?
Keep windows closed during high pollen counts (typically early morning and evening). Monitor pollen forecasts and enjoy fresh air on low-count days. Consider window screens that filter pollen if you prefer open windows.
