Healthy Air at Home

Understand first

Education-first • not medical advice

Why this matters (expanded)

What’s going on

Indoor air quality is shaped by particles (dust, pollen, smoke), moisture (damp/mould risk), and gases (cooking fumes, fragranced products). The aim is to reduce exposure in the rooms you actually use.

Why it matters

Poor air can worsen comfort and may aggravate allergies or asthma in sensitive households. You’ll usually notice benefits as “less stuffy”, fewer morning symptoms, and more comfortable sleep.

Common causes

Poor ventilation (especially in winter).
Cooking fumes without extraction.
Damp bathrooms/bedrooms and slow drying laundry indoors.
Fragranced sprays/candles adding irritants for some people.

No-spend first steps

Ventilate strategically: short, intense airing + extractor use during cooking/showering.
Keep humidity in check (roughly 40–60% if you can measure).
Dry laundry with airflow; don’t block radiators.
Dust + vacuum regularly, especially bedrooms.

If you’re buying anything, use this calm checklist

If buying a purifier: match CADR to room size; HEPA matters; noise matters.
If damp: measure humidity first; a dehumidifier can help targeted rooms.
Avoid “ioniser/ozone” style claims; keep it simple.

Ventilation: open‑window habit, especially after cooking/showering.
Humidity: target 40–55% RH to limit mould/viruses.
Particles (PM2.5): from cooking, candles, dust; reduce and capture.
Chemicals/VOCs: favour fragrance‑free, low‑solvent products.

Quick checks

Steam on windows? Increase ventilation or use extractor longer.
Musty smell? Inspect cold corners, behind furniture; keep 5–10 cm gap from exterior walls.
Greasy film in kitchen? Use lids, rear hobs, stronger extractor setting.

Low‑cost moves

Microfibre + HEPA vacuum weekly.
Pan lids & back burners reduce PM.
Fragrance‑free cleaners; avoid aerosol sprays.
Door‑open purge: 5–10 min cross‑breeze after high‑pollution activities.

Purifiers (small rooms)

Choose HEPA‑class filter with stated CADR.
Place near source (bedside, desk).
Replace filters on schedule; keep a calendar reminder.

Humidity set‑up (winter)

Use a hygrometer. Add a humidifier only if RH <35% for long periods.
Clean tanks with vinegar weekly; use distilled water to cut mineral dust.

Plants?

Nice, but rely on ventilation + cleaning for real air quality gains.

Sleep routine

Air room 10 minutes, quiet purifier on low, keep RH ~45%.
