If you’re an allergy sufferer, you should consider investing in an allergy-friendly vacuum to reduce the amount of dust circulated by a standard vacuum cleaner.
Easy Solution: Use an allergy bag in your vacuum to improve filtration. Compared to a standard vacuum bag, allergy bags are double-lined, making it easier to trap fine dust.
Vacuums that include a filter behind the bag trap allergens that may pass through the bag. A washable foam filter or a finer electrostatic filter are 98% efficient and inexpensive to maintain.
For the finest filtration, consider purchasing HEPA filters (high efficiency particulate air). Severe allergy sufferers should consider HEPA filters which work best on models that are more powerful and have a completely sealed system. This particular type of filter normally costs between $20 and $80 and should be replaced at least once a year.
