The quick answer

Viruses aerosolize, meaning they float in the indoor air for hours after a cough. To protect your family, do not use chemical aerosol sprays (Lysol) which trigger asthma. Instead, dramatically increase your home's Air Changes per Hour (ACH) by cracking windows, and run an oversized True HEPA Air Purifier (like the Coway Airmega or Levoit) continuously on high in the main living space to physically scrub the viruses from the air.

01

Mechanical vs Chemical Scrubbing

Lysol kills viruses on surfaces, but it does virtually nothing to clean the air you are breathing, and the chemical fallout from the spray is disastrous for infant lungs.

True HEPA filters are mechanically dense enough to trap microscopic viral droplets (down to 0.1 microns). By physically pulling the air through the filter, you subtract the viral load from the room dynamically.

True HEPA filters are dense enough to trap viral droplets down to 0.1 microns, while aerosol disinfectants like Lysol do virtually nothing to clean the air you breathe.

In short

  • HEPA filters physically trap aerosolized viruses.
  • Aerosol disinfectants are asthma triggers, not air purifiers.

The bottom line

Ventilation is your deepest defense against respiratory viruses. Crack a window, turn your HVAC fan to "ON," and deploy a HEPA purifier in the playroom.

QDo UV light sanitizers work?

Yes, but only if the air moves slowly enough across the bulb. Most consumer air purifiers with tiny UV bulbs are just marketing gimmicks.
