If the air in your home is too humid, and you have asthma, it can be like breathing soup.

Also serious, is that humidity can encourage many kinds of allergens in your home. dust mites, molds and some fungi thrive in humid areas of your home. The peak season for these allergens are summer and fall - just when seasonal allergies may also be the worst.

The combination for people who have allergy-induced asthma can be deadly.

This is where dehumidifiers can be extremely important, whether you have allergies or asthma. At the very least, a dehumidifier supports you in making your air easier to breathe. At the best, it is also a useful tactic in the fight to keep your home's air as allergen free as possible.

Depending on your needs, you can purchase either a built-in dehumidifier or a portable dehumidifier. If your biggest concern is asthma (but not allergies), a room dehumidifier could be sufficient. It might be ideal in your bedroom to keep the air there as easy to breathe as possible. No one wants to wake up from sleep with a breathing problem.
If your biggest concern is allergies to dust mites and the like, you might want to look at a whole-house solution. Dampness can be a problem in any room, whether it's occurring between a set of blinds and the window when the air conditioning is on, or in your basement since the walls sweat.

When looking for a dehumidifier consider the following options:

  1. Total capacity of water the dehumidifier is capable of removing before full.
  2. Automatic shut off when the tank or pan is full.
  3. Automatic reset when the drain pan or tanks have been emptied.
  4. Size of room the dehumidifier will be servicing.
  5. Adjustable humidity controls to vary the amount of moisture removed from the air.
  6. Automatic signal light to identify when the dehumidifier is in operation.
  7. Hose threads into the drain pan or tank for easy attachment without leaking.

For those with allergies, beware of deodorizing filters that can add a fresh scent to the air. Those who have a tendency for allergies can develop new allergies over time. Chemicals and fragrances can be likely culprits.
