Portable dehumidifiers are available in a variety of moisture-removal capacities (usually identified as pints of water removal daily), to accommodate small or large spaces. There are also whole-house units available. Learn more about newer Bionaire models.

This depends entirely on the humidity level in your home or business. Monitor water levels in the container to determine how frequently you'll need to empty and clean your dehumidifier's water container.

If there is no more moisture there the dehumidifier can't collect it.

One of the primary culprits behind allergy symptoms in homes is excess moisture. Too much moisture in your indoor environment creates a breeding ground for mold, mildew, dust mites, and bacteria. All of these can irritate allergies, causing itchy eyes and skin, respiratory problems, and many other uncomfortable symptoms. By using a dehumidifier to remove the excess humidity from your indoor environment, you can create an overall healthier environment and help control your allergy symptoms.

Dehumidifiers have a cooling system that refrigerates the air entering the unit. The moisture in the air condenses on the cold coils and then deposits into a removable container (water container, water tank or water reservoir) located at the bottom of the unit. The cold air is then passed over a warm set of coils, which warms the now-dry air back to its original temperature.

Most homes and businesses in humid climates can benefit from the use of a dehumidifier. There are some obvious signs, too. Symptoms of excessive humidity include moisture marks on walls and ceilings, warped or damaged wood (wood swells in high humidity conditions) peeling wallpaper, blistered ceilings, creaky floors, sticking doors and cabinets, musty odors and mold growth. Of greater concern may be symptoms of mold and mildew allergies.

A humidity level between 30%RH and 50%RH is recommended. A hygrometer is a measuring device that measures humidity. Hygrometers can be purchased on your local retailer.

90% of homes can produce 3- 5 pints per day, but every home is different. For example, it's not unusual to find next door neighbours in almost identical homes with the same family size producing different amounts of moisture. There's no hard and fast rule about how much moisture to take out, but you will soon know if your dehumidifier is working effectively as condensation will start to disappear and your home will feel much drier and healthier. There are other unseen benefits too, including a reduction of moisture levels in your furnishings and walls, less mould and fungal spores and fewer house mites - all of which can provoke allergies, and aggregate asthma and arthritis. You might also find that your laundry dries quicker with a dehumidifier in your home, which is a welcomed benefit in winter or if you live in an apartment that has no outside drying space.

Proper placement of your dehumidifier is critical for achieving top performance. Most people place dehumidifiers in basements, laundry rooms, crawl spaces, and indoor pool areas since these areas often have moisture problems. However, there are models available to address a variety of moisture issues that can be placed anywhere-from single bedrooms to large rooms. Once you have determined the area that needs dehumidifying, narrow down the specific part of that area where the dehumidifier will physically be placed. Most manufacturers recommend placing your dehumidifier at least six inches away from walls or any other structure that may impede airflow into and out of the dehumidifier.
