Mechanical exhaust ventilation systems with natural fresh air flow are designed to rely on exhaust fans installed in the kitchen and the bathroom.

The fresh air is supplied to the habitable inner spaces i. As the air gets dirty it gradually drifts into the bathroom and kitchen through the internal doors and then is removed outside by the exhaust fans. The outdoor deflector prevents water ingress into the premises and has a mosquito screen for insect control. The filter removes dust and contamination from the supply air, retains excess moisture and partially blocks off the street noise.

The adjustableposition indoor grille allows varying the supply air volume and flow direction. Dirty filters increase air resistance in the system and reduce supply air volume. The filters require cleaning not less than times per year. Vacuum cleaning is allowed. After two consecutive cleanings filters must be replaced. The ventilator is equipped with a regulator allowing various combinations of air flow intensity and direction so that the resulting microclimate offers maximum occupant comfort.

It will also damage and destroy common building materials like wood and gypsum board. Mold in a bathroom can be caused by a plumbing leak, but splotchy stains on wall or ceiling surfaces usually indicate inadequate ventilation—too much moisture in bathroom air. This can also cause mold to form on wood or insulation in an attic space above a bathroom. While there are other reasons to solve bathroom ventilation problems—the inconvenience of foggy mirrors, for example— preventing mold is the most compelling reason by far.

Understanding these elements will help you make the right decisions about bathroom ventilation, whether straightforward or complicated.

Bath fans are sized according to the volume of air they can move, measured in cubic feet per minute, or cfm. The rule of thumb is that you need 1 cfm for every square foot of floor area in your bathroom. Better fans are engineered to run quieter than low-priced versions. Look for a sone rating of around 1, as opposed to 3 or 4. A bath fan that includes a light will eliminate the need to install a separate ceiling fixture.

The point here is that all fans are not created equal. Opting for special features can help you cope with challenging ventilation conditions. It can crush or tear easily, which will impede air flow. This rule applies to any type of ductwork. All of the options discussed below have been used to solve difficult bathroom ventilation problems.

But these unconventional installations are best handled by an experienced HVAC contractor.

Bath exhaust fans are about keeping your house in top shape by moving water out of your bathroom. Water is everywhere in a bathroom: splashing on the floor, beading up on the walls, dripping down the mirror.

And there is one other invisible place where you will find water in the bathroom: in the air. Venting fans pull moisture-laden air out of that small space, slowing or altogether preventing it from condensing on walls, on the ceiling, or worst of all, inside the ceiling itself. It can be an ugly sight to crawl above a poorly ventilated bathroom's ceiling.

You might find mounds of black-moldy blown-in insulation , as well as joists and rafters weakened from years of moisture abuse.

When moisture spreads in a home, one thing quickly leads to another. When these cellulose-hungry insects begin feeding on your home's wood framework, you need to act quickly. Costs spiral from there as you put the home under a pest control contract and undergo extensive remodeling work to shore up weakened studs.

When the fan is located directly above a shower or bathtub, it needs to be connected to a GFCI-protected circuit. Because windows provide light as well as ventilation, if you go the fan-only route you need to install artificial lighting. This should already be a given, as electrical code requires that habitable rooms be supplied with a switch-controlled light.
