HEPA (which stands for high-efficiency particular air) filters are designed to trap allergens in the air and create spaces in the home where you will not be affected. If you suffer from a pollen allergy, HEPA filters scan be applied to the windows on spring and summer days, stopping allergens from coming inside and setting off your allergies.
These filters are ideal for those who like to enjoy the fresh air but who don’t like the effect it has during the summer. As well as HEPA filters, HVAC (air conditioning) systems can help create a cool environment indoors without allowing allergens to come in through the window. There are lots of filters and systems available on the market, designed to suit all budgets.
