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.
For dust allergy, remove drapes, feather pillows, upholstered furniture, non-washable comforters and soft toys. Replace carpets with linoleum or wood.
