In the bathroom, you would want the dehumidifier closer to the shower area, where there is lots of mist coming out of the shower. A portable dehumidifier like the Morris 20L Silent dehumidifier can be placed on a countertop next to your hot water sink.
It's best to place it somewhere central in the house, being sure to think about where your sources of moisture are. Moisture problems like damp and mould are typically likely to arise in the bathroom, where showers and baths create lots of steam. And so, it is best to position your dehumidifier on the landing.
A dehumidifier is recommended more for use in the bathroom when your humidity levels are persistently high. This means those times when everyone is using the shower or bath yet the room remains continually humid.
Keep Your Dehumidifier Away from the Walls
It's easy to assume the best place to put your dehumidifier is against the wall. But it's not! Dehumidifiers suck in and expel air using vents. Blocking any of these vents can reduce your dehumidifier's effectiveness.
The water is drained by gravity alone so for effective continuous drainage the dehumidifier needs to be raised a foot or two above the floor and the hose run to a floor level drain.
Firstly, it's worth noting that the most effective place to position a dehumidifier is in the centre of a room. This allows the air to circulate properly around the unit. The only time when this positioning can be disregarded is if the unit has a top-mounted air discharge.
The bigger the dehumidifier (and the higher the wattage), the more watts it'll generally use. Large ones can use up to 500 watts, while the smaller models usually only use about 22 watts. All of these factors can also impact your dehumidifier's energy use.
Placement is key. Be sure to allow enough room for air to freely flow into and out of the dehumidifier. Most of the models in our ratings release air through vents on the top, but a few vent out the side.
A dehumidifier should collect a certain amount of water each day - generally, around 10-20 pints of water per 24-hour period. This should require you to empty most dehumidifiers daily or bi-daily when in operation.
Cons of Dehumidifiers
Dehumidifiers collect water meaning they need to be regularly emptied. They also need to be regularly cleaned otherwise black mould can start to grow on the machine , which can induce a wide range of health problems including allergic reactions, lung problems and irritation.
Best Dehumidifier For Bathrooms
The best dehumidifier for bathroom use we've tested is the Midea MAD50PS1WS. This full-size unit has a substantial 50-pint capacity and will quickly deal with ambient moisture even within large bathrooms.
You should keep it on for several minutes after you get out of your shower in order to eliminate the most amount of bathroom condensation possible. Dehumidifiers are available in a variety of prices as well, so if you happen to be on a budget, there are always affordable dehumidifiers to choose from.
'Fans are more efficient at preventing moisture build-up during and immediately after a shower, whereas dehumidifiers are better at maintaining a lower humidity level over time.
Using a dehumidifier in the bathroom becomes a smart choice if your humidity level is always high, even when you aren't showering. You can sleep well at night knowing that you won't unintentionally affect other rooms in your home since placing a dehumidifier in your bathroom won't affect other areas.
Dehumidifier Size
Small portable dehumidifiers are inexpensive, quiet, and effective for areas that measure 400 square feet or less. A small-capacity unit is generally capable of removing 30 or fewer pints of moisture from the air per day. This is more than enough for a bathroom, small home office, or a large pantry.
Should a Dehumidifier Run Constantly? No, your dehumidifier should not have to run constantly to regulate the air humidity. An optimal humidity level to shoot for is between 30 and 50 percent. Your dehumidifier should reach this in 8 to 12 hours.
Strategically Position Your Dehumidifier:
Avoid positioning the dehumidifier too close to walls, as this can hinder air intake and increase energy consumption. Keep it away from doors, windows, and air vents to prevent drafts. For targeted moisture problems, place the dehumidifier close to the source.
To empty your home dehumidifier, you have to carry a bucket of water from your dehumidifier across the room and pour the water into a corner drain or the laundry sink.
A dehumidifier makes the external conditions less welcoming to mold; by removing moisture, they reduce the chances of mold growth. An air purifier, however, removes mold spores from the air, making it harder for mold and mildew to create new colonies.
Position the dehumidifier in a central area of a room or your home. 'Placing the unit centrally will allow a more even distribution of dry air throughout the space, which is especially important in larger rooms or open-concept living areas,' explains Fantastic Services' HVAC and appliance technician, David Miloshev.
That brings me to my next word of advice: A dehumidifier must be installed on a level base, preferably raised off the crawlspace ground level at least 4 to 6 inches, so that the condensate can drain properly into a condensate pump or a gravity drain carrying the condensate out of the crawlspace.
Well, according to Isaac Newton, in his book Opticks, (and USA Today) humid air is actually LESS dense than dry air. It makes sense. If humid air didn't rise, why would rain fall from the sky when the temperature drops? So, in a home, humid air rises up, not down.
So, it really depends on your end goal and needs. Is it cheaper to run a dehumidifier or air conditioner? Yes, dehumidifiers cost significantly less to run.
You don't always have to run the Dehumidifier at such a low humidity. Usually a setting of 40 to 50 percent is adequate depending on the conditions.
