When the filters do not work properly, allergens may be released into the air, causing typical allergy symptoms, such as watery eyes
, runny nose, and wheezing. Wash
shower curtains, bathroom tiles, and grout regularly and use a dehumidifier in your house.
Also remove drapes, feather pillows, upholstered furniture, non-washable comforters and soft toys. Replace carpets with linoleum or wood. Vacuum (with HEPA filtered vacuum cleaners) soft furniture and curtains as well as floor.
