If you have allergies or asthma and you have carpet, there's a good chance your floors are contributing to your symptoms. Carpet is extremely effective at trapping airborne allergens — which sounds like a good thing until the fibers become saturated and those allergens get released back into the air every time someone walks through the room.

What's Actually Living in Your Carpet

A square yard of carpet can hold several pounds of trapped particles. Common allergens found in carpet include:

Dust mites — the #1 indoor allergen trigger. Dust mites thrive in warm, humid environments and feed on dead skin cells. A single gram of dust can contain thousands of dust mites and their waste particles.

Pet dander — microscopic skin flakes from dogs and cats that remain airborne for hours and settle deep into carpet fibers

Pollen — tracked in from outside and deposited throughout the house

Mold spores — especially in basements or areas with humidity

Cockroach allergens — common in Ohio homes and highly allergenic

Bacteria and VOCs — tracked in from outdoors and from household activity

Why Vacuuming Isn't Enough

Regular vacuuming removes surface debris and some allergens from the top layer of carpet. But it doesn't reach the allergens embedded deep in the fibers and carpet backing — and it can actually stir up fine particles like dust mite waste into the air if your vacuum doesn't have a HEPA filter.

What Professional Hot Water Extraction Does

Professional steam cleaning (hot water extraction) is fundamentally different:

High heat — 200°F+ steam kills dust mites, bacteria, and mold spores on contact

Deep penetration — solution reaches the carpet backing where allergens accumulate

Powerful extraction — suction removes the dead mites, waste particles, pollen, and pet dander from deep in the fibers — not just the surface

Deodorizing — removes odor-causing bacteria that can trigger respiratory sensitivity

Multiple studies have found that professional carpet cleaning significantly reduces dust mite concentrations and allergen loads. The IICRC recommends professional cleaning every 6–12 months for households with allergy or asthma sufferers.

Columbus-Specific Factors

Ohio has some of the highest pollen counts in the Midwest, particularly in spring (tree pollen) and fall (ragweed). Columbus residents track these allergens inside constantly. The Ohio humidity also creates ideal conditions for dust mites and mold growth in carpet.

If you notice allergy symptoms are worse at home than outside, or worse after walking across certain rooms, carpet allergens are a likely factor.

Tips for Allergy Sufferers

Clean every 6 months rather than the standard 12–18 months

Vacuum with a HEPA-filter vacuum 2–3 times per week

Control humidity — keep indoor humidity below 50% to reduce dust mite activity

Remove shoes at the door to reduce pollen tracked in from outside

Ask about allergen-neutralizing treatment — we offer a post-cleaning treatment that further reduces dust mite and allergen activity
