Do you need an air purifier or a different fix?

Coway Airmega 400

Coway Airmega 400

Start by removing or exhausting the pollution source. A vented range hood beats a purifier for cooking, a compatible HVAC filter can cover several rooms and dry-air or mold problems need their own fix. For recurring particles in one closed room, the Coway Airmega 400 is the safest broad starting point here.

What matters in practice

How to choose for this need

Fix the source first, then add filtration only for the pollution that remains.

01

Cooking starts at the range

Use a vented hood when possible. A room purifier can collect escaped particles, but it cannot capture heat, moisture and gases at the burner as effectively as source exhaust.

02

Central filtration can cover more space

A compatible higher-efficiency HVAC filter treats the air moving through the central system. Check equipment limits before increasing resistance.

03

Some problems are not filtration problems

A purifier does not lower humidity, repair water damage, stop a combustion leak or replace a carbon-monoxide alarm.

Check these before buying

  • Identify the pollutant
  • Remove or exhaust its source
  • Check the central system
  • Size a room purifier only for the remaining need

What this comparison cannot tell you

  • Opening windows can worsen indoor air during smoke or high-pollen periods
  • Do not improvise a filtered fan setup without a stable, current safety design
