How to Use Filters to Reduce Dander in a Home

Dander is composed of the particles that come off the fur and skin of an animal, and it is known to cause allergic reactions in some people who are prone to allergies. Every animal sheds some form of dander, but certain animals like rabbits and cats are known to cause more profound reactions than dogs. While the only way to prevent dander from getting into your home is by not having a pet, it's possible to user filters to reduce dander.

Difficulty: Easy

Instructions

1. Set aside rooms in your home where your pets are not allowed. This will help reduce the need for air filters in certain areas. One of the first places that pets should not be allowed is in your bedroom, as dander can embed itself in your sheets, comforter and even your closet (coating all of your clothing).

2. Measure the square footage in your home. The square footage in your home will give you a good idea as to what volume of air you need to filter, and how many filters (and of what size) are required to clean the air properly. Smaller filters are fine for studio apartments and smaller rooms, but for a home with spacious rooms, you'll need several filters to keep the air scrubbed.

3. Use a high-efficiency particulate air filtration system (HEPA, for short). A HEPA filter is rated to remove even the tiniest particles from the air, making it possible to remove dust and dander from the ambient atmosphere. A HEPA filter is also perfect for use in an air conditioner because of its power and ability to move a large volume of air.

4. Use your air filters in locations where they have the best chance of moving the most air. Positioning an ionic filter near a wall is efficient, but finding a spot for it closer to the center of the room is better.

5. Replace your central air conditioning unit's air filters on a regular basis. Once a year is usually enough to keep a central air conditioning unit running at peak efficiency.

Tips & Warnings

• Invest in new windows to help reduce the amount of allergens that can leak in from outside. Double-paned windows with fresh gaskets can help dramatically, although this is a major expense and one that should really only be considered by those with severe allergies.
• Be aware that some filters require constant replacement or cleaning in order to remain effective. For example, standard air filters should be replaced every 1 to 2 months, and filter-less air filters (like ionic air filters) can usually go for a few months without requiring wiping.
