Indoor Air in a Small Apartment: What Actually Helps
Compact apartments trap cooking smoke, dust and pollutants from outside. A few changes make more difference than expensive gadgets.
Many New Yorkers spend most of their day indoors, and small apartments can hold a surprising mix of pollutants: cooking fumes, dust, pet dander, moisture and whatever drifts in from the street. Improving indoor air does not require a large budget, but it does require knowing which measures work.
Ventilation comes first
Fresh outdoor air is the basic way to dilute indoor pollutants. Open windows when outdoor air quality is good, and use exhaust fans while cooking. Running the bathroom fan during and after a shower helps limit the damp that can encourage mould.
Where a purifier helps
A portable air purifier with a true HEPA filter removes most airborne particles in the room where it runs. It does not clean gases or odours well on its own, so it works best as a complement to ventilation. Place it in the room where you spend the most hours, usually the bedroom or the main living area, and keep it on a setting that matches the room size.
What to avoid
Be cautious with products that promise to purify the air through ionisers or sprays. Some ionisers can produce ozone, and many scented products add their own chemicals. Keep filters changed on any device, because a clogged filter stops working.
Cooking and cleaning
Cooking is one of the largest sources of indoor particles in a home. Use the hood, cover pans where practical, and clean the filter regularly. Choose low-odour cleaning products where you can, and ventilate while using them.
This is general information. People with asthma, allergies or other breathing conditions should follow the advice of their clinician about managing indoor triggers.
