As homes are remodeled and laundry rooms are created where there wasn’t one before, contractors have had to get very creative with how to vent the dryer from the laundry room to the exterior of the home as required by building code. Sometimes it’s not possible to vent to the outside. In this case, contractors may recommend an “Indoor Dryer Vent Kit.” These kits can be easily found in hardware stores, big box stores and online.
The manufacturers of these products claim to solve the problem of venting a dryer to the exterior of the home. They also claim that Indoor Dryer Vent Kits are ideal for apartments, condominiums and RV’s.
However there are some down sides. Here are some things you may want to take into consideration if you use this product.
How do these Indoor Dryer Vent Kits work?
The flexible dryer exhaust hose is simply routed from the back of the dryer into the reservoir of these Indoor Dryer Vent Kits. Water is placed inside the reservoir. The theory to this product is that the water acts as a filter and catches the lint. The homeowner is supposed to change out the water after every load.
Eight problem with Indoor Dryer Vent Kits
1) Just because a product is sold in a big box store doesn’t mean that it meets building code. In fact, the 2016 California Mechanical code 504.4 specifically says: “Clothes dryer exhaust ducts shall (meaning required to) terminate to the outside of the building.” Many states have this same code. This means that Indoor Dryer Vent Kits are against code in California and in fact, in most other states. Before purchasing, check your state and local mechanical codes to determine if these products are legal to use in your area.
2) For every load of laundry you dry, you are venting up to a gallon of water in condensation from your dryer. This will create a sauna in your laundry room. The water reservoir for an Indoor Dryer Vent Kit doesn’t prevent that moisture from exhausting into that room. In fact, the humidity in that room can get so bad that your walls and ceiling will be dripping with moisture. Eventually the paint will bubble and peel. The extra moisture will also ruin wood cabinets in the room. Opening up a door or window in the laundry room may not be enough to solve the excessive moisture issue.
3) This extra humidity and moisture will create mold problems in your home since the moisture is getting into the drywall and wood cabinets.
4) Lint can pass through the Indoor Dryer Vent Kit’s reservoir without going into the reservoir water which means the lint will coat your laundry room and house with a fine layer of lint. The lint doesn’t necessarily get trapped inside that water reservoir. When lint accumulates inside a room, the buildup can create a fire hazard. And of course, it creates a mess too.
5) There have been documented complaints that the fine particulates of lint that escape from the reservoir can cause the smoke detector to go off.
6) Even more dangerous, the manufacturers of these Indoor Dryer Vent Lint Kits warn homeowners not to use this device with gas dryers. Many homeowners either don’t realize this hazard or may not even know if they have an electric dryer or gas dryer. Venting your gas dryer inside a home is like running your car in the garage with the garage door closed. This could prove deadly.
7) The hassle factor is huge. The manufacturers of the Indoor Dryer Vent Kits recommend to change the water inside the reservoir after every load. In reality, when we go to a house that has been using this set-up, the water hasn’t been changed for weeks or months since it’s such a nuisance to deal with.
8) Since most of us now live in airtight homes, the lint particulates migrate into the entire living area. It is then in the air you breathe. For people who have asthma or allergies, this can be a major health hazard. Why take the risk?
