PuriFresh® Ventilation Products are designed to provide healthy indoor air to everyone,
but specially to people who suffer from allergies and asthma.
Ventilation is a basic need for your health, yet ventilation is poorly understood
by the public. Ventilation is often confused with circulation. Ventilation is exchanging
indoor air with outdoor air. Circulation is only moving indoor air around the room
or around the house. Even among those who understand the concept of ventilation,
some think that opening the front door several times a day is sufficient ventilation.
No! Opening the front door will provide, at best, several tens of cubic feet of
ventilation, the amount required, each minute. You would have to open and close
your front door once a minute to provide proper ventilation to your home.
Think about that, and think about how much cold (or heat and humidity) you are letting
in, depending on the season. If you suffer from seasonal allergies, think about
how much pollen you are letting in.
PuriFresh® Ventilation Products, exchange heat and moisture while ventilating, so
your do not let in cold or heat and humidity. If you are an allergy or asthma sufferer,
our Fresh-Air System also keeps out almost all particulates.
