Significance Of Bathroom Ventilation

Bathroom fans are essential in today’s designs of air tight and energy-efficient homes and assist in the prevention of humidity issues.   Proper ventilation is important  when it comes to the  overall health of the homeowner and assist in the structural integrity if the home.

The biggest problem with bathrooms is the high humidity level. Humidity is simply the amount of water vapor in the air. Warm air holds more humidity than cold air. These may be adversely affected in the bathroom by the presence of microbial hazards that grow in damp and dark areas, such as poorly designed bathrooms.

For bigger bathrooms it is recommended to have a bathroom fan, which is an exhaust fan that pulls excess moisture away from the  interior to be vented outside the building. In this way, the humidity and moisture inside the bathroom reduce the risk of growth of mold. However, be sure to check that the bathroom fan is strong enough to pull moisture outside the bathroom, and a simple way to test this is by holding up a tissue to the fan. If the tissue falls down, the fan is not strong enough.

Structural Damage

Moisture vapor can peel wallpaper or paint off the surfaces and encourage the growth of mildew and mold. Moist air can condense inside the wall cavity, where it can cause rot, mold and serious structural damage to wall studs, sheathing, and ceiling and floor joists above and around the bathroom.

 Timer Switches

Ventilate and control all fans with timer switches.  In my professional opinion,  the best  and most cost-effective way to remove humid air from showering is to replace your light / fan switch with an automatic timer switch.  It’s designed so that the fan goes on when you set the timer, then shuts off when the time runs out.

Using a timer switch allows you to remove humidity for up to 30  minutes  or more depending on the model after you leave the room, without the worry of forgetting to turn the fan off.

Home Maintenance Tips for: Cleaning Bathroom Exhaust Fans

 

Have you ever turned on your bathroom exhaust fan to hear it suddenly make a strange squeaking sound or maybe even stop working completely? Chances are the motor to your unit  may just need a simple cleaning.  These units should be put on a maintenance cleaning schedule about every three-month as they do get quite dirty and dusty inside. Regular cleaning extends the life of the motor inside the unit and keeps it working properly.

Exhaust fans unit play an important role in all bathrooms as they:

1- keep your walls dampness to a minimum to prevent damage to the drywall and to circulate the air

2- prevents and keeps mold growth to a minimum since bathrooms are usually a higher moisture and humidity content than any other room in the home especially after hot baths and showers

3- provide an escape route usually for strong offensive odours

Below are simple cleaning instructions to assist you if you are planning on doing it yourself!

Depending on how long it’s been since the last time you cleaned your bathroom exhaust fan, now is the time to pull out the vacuum cleaner before removing the cover. You will save yourself from a great deal of dust falling on to your bathroom floor if you vacuum the bulk of the dust off before you remove the cover.

Start by choosing the brush attachment and begin by gently removing the accumulation of cobwebs and dust that has collected substantially over time.

If your plan is  just doing an ‘in between clean’ of your  fan cover once every couple of months, you can stop here and not worry about doing a detailed clean of the cover and fan.

Once you have vacuumed up as many dust bunnies as you could manage, make sure someone who knows what they are doing has turned the bathroom power off at the mains, then put on some gloves, climb carefully up your ladder and pull off the fan cover. Most will come off fairly easily, but some may need screws removed with a screwdriver.

Choose a  quality cloth to ensure you don’t just spread the grime and wipe off as much surface dust as you can, taking care not to damage or pull on the fan.

Next, take the fan cover, spray with an all-purpose cleaner and give it a once over with a small scrubbing-brush. If the ingrained dirt doesn’t seem to be releasing after this, give the cover a soak for a few minutes in some warm water to loosen the dirt and try again.

Once everything is clean and dry, put it all back together and enjoy knowing that your  bathroom exhaust is now working at peak efficiency and will continue to operate for years to come!
