Maintain/clean dehumidifiers and air conditioners regularly. Air
filters of the
ac trap allergens, like molds, dust and pollen. 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.
