Please follow the link here to our INSTRUCTIONAL VIDEOS for installation, calibration and cleaning help. Below are some answers to frequently asked questions.
Anyone who can not vent their electric dryer to the outside. Homeowners that have a dryer exhaust line that exceeds the manufacturers recommendations. Homeowners that want to save energy by using the warm air from the dryer to help heat their home.
Anyone who is currently using one of the water trap models should consider switching to a BetterVent. Download a copy of the BetterVent Installation Brochure here.
Our double filter system DOES NOT USE WATER and captures more dust and lint from your dryer than any other dryer vent system currently on the market. Your home will have cleaner air and better indoor air quality.
The best place to install the BetterVent is on a wall as close to your dryer as is convenient. You will want it about eye level so that it is easy to access and clean. Also, the shorter the exhaust hose is, the more efficiently your dryer will operate.
It must be installed in an upright, vertical position with the standard 4" exhaust hose coming out the bottom. The other end of the duct is then connected to your dryer's exhaust port.
You should plan for adequate ventilation in the laundry area as small spaces can create excess moisture if the air is not able to escape the room.
Something as simple as a small fan or open window will go a long way to resolving any issues.
You should be sure to clean out any lint from the dryer cabinet itself before installing and calibrating your BetterVent. Lint buildup affects the operation of your dryer, making it take longer to dry clothes.
Lint can also infiltrate to the inside of the dryer cabinet and become a fire hazard (even if you vent to the outside).
Pull the dryer away from the wall and vacuum out the exhaust port where the duct attaches and any of the openings inside the dryer itself that you can reach. This will improve the performance of your dryer.
Everything that you will need to install and begin using it right away is provided, It includes instructions, mounting hardware, 4 calibration weights and 2 polyester filters (1 to use now and 1 spare).
The kit DOES NOT include the transition duct hose, hose clamps, or close elbow.
First of all, you should use a transition hose that is UL listed. The best type of transition hose, recommended for use with most newer electric clothes dryers which tend to run a bit hotter than older models, is a semi-rigid aluminum 4" transition duct.
Also acceptable would be an all aluminum UL listed flexible transition duct (also known as a "slinky" type).
This type is best used with a close elbow to prevent it from getting crushed behind the dryer. NEVER USE THE WHITE VINYL FLEXIBLE HOSE!
We do not recommend installing it through a wall to heat other rooms. BetterVent should remain accessible in the dryer area for filter changes and monitoring. If your goal is to recover heat, the safer approach is to keep the unit accessible in the laundry area and use a fan to help distribute the heat throughout the area.
BetterVent does not contain electronics, wiring, motors, or moving powered components. It is essentially a passive plastic ABS duct, so many of the certifications customers commonly ask about, such as UL electrical listing or FCC certification, are not applicable. That said, code requirements can vary depending on where and how it is installed, so if your project requires a specific certification or code approval, we recommend checking with the local authority having jurisdiction or your HVAC/building professional.
The Safety Exhaust Flap (SEF) is there as a backup airflow path. If the BetterVent's normal outlet path becomes restricted or blocked, the flap can open to let air escape instead of forcing pressure to build up inside the duct system. In normal operation, the flap stays closed and the airflow is directed through the BetterVent. It is not a motorized or electronic part; it is simply a passive safety feature designed to help relieve airflow if there is restricted airflow.
BetterVent filters are sized and selected specifically for the BetterVent housing, so we recommend using the official replacement filters to ensure proper fit, airflow, and performance. Generic filters may look similar, but if the size, thickness, or material is different, they could restrict airflow or fail to capture lint properly. Replacement filters are available directly from us.
The BetterVent should be installed upright and off the floor so the patented Safety Exhaust Flap and filter can function properly and so lint and moisture do not collect in the housing. We do not recommend installing it sideways, laying it flat on the ground, or placing it low where it may be blocked, kicked, exposed to standing moisture, or harder to monitor and clean. For best performance, mount it vertically in an accessible location with enough clearance to open the front and replace the filter.
Place the filter flat inside the filter frame so it fully covers the opening. Make sure it is seated evenly with no folds, gaps, or edges sticking out. Place the colored side of the filter towards the inside of the BetterVent. The colored side is more robust so if you would like to shop vac the filter, you can do this several times before needing to actually replace the filter. Close the front door securely.
Clean the magnet area, press the magnets fully back into place, and make sure the door lines up without being forced. If a magnet keeps coming loose, use a small amount of strong plastic/metal adhesive and let it cure fully before running the dryer.
There isn't a fixed number of loads, because it depends on what you're drying, lint volume, dryer size, cycle length, and how full each load is. Check the filter regularly and replace it when it becomes visibly loaded with lint, damaged, or when you notice reduced airflow or longer drying times. Heavy lint items like towels, blankets, fleece, pet bedding, or new fabrics may require more frequent changes.
Use a vacuum, lint roller, or gently remove lint by hand. Do not wash the disposable filter with water, because it can mat the lint into the filter and affect airflow. Replace the filter when it is heavily loaded, damaged, or airflow is reduced.
Reuse it only while it stays flat, intact, and airflow remains strong after cleaning. Replace it if it becomes matted, damaged, clogged, misshapen, if drying times increase, moisture builds up, airflow seems reduced, or the safety flap is opening more often.
We understand the concern. The price isn’t just for the raw material; it also includes the custom sizing, packaging, inventory handling, and fulfillment of a small replacement kit. We offer them so customers can restore the flap to the proper balance without replacing the whole unit.
Because the BetterVent vents electric dryer air indoors, some moisture will enter the room. The best way to manage it is to increase ventilation: open a window, run an exhaust fan, set up a fan to move air out of the space, or use a dehumidifier while drying. Also keep the filter clean so airflow stays strong. If moisture or condensation remains excessive, that space may not be a good fit for indoor dryer venting.

Humidity issues with indoor venting are really very specific to the home situation. You should expect the dryer to discharge a moderate amount of warm moist air into the room for about half the dryer cycle.
By the end of the cycle there is no more humidity. Unlike other indoor dryer vents on the market ours does not require a water trap to capture dryer lint.
This means that the amount of additional humidity that would be added to the air by models that use water does not exist with the BetterVent.
We recommend ventilation and circulation of the room air if you experience condensation issues in the laundry area. This can be accomplished with a small room fan, opening a window, turning on a nearby ceiling ventilation fan (such as those found in bathrooms).
Making sure that your washing machine is spinning out as much of the water as possible before drying will make a big difference in how much moisture is put into the room.
Adding an extra spin cycle if the clothes are still really wet can be helpful in reducing the amount of humidity coming from the drying clothes.
Silica Gels, and products such as DampRid or Humydry can also help. In extreme cases a mechanical dehumidifier may be needed.
There are a few things to take into consideration with installation of dryers in tight spaces, the main one being condensation.
You will need to have enough air circulation in the area to keep condensation from settling on the surrounding walls. If you have the opportunity to install a ceiling vent fan such as those used in bathrooms it would be a valuable asset in this situation.
A small fan mounted on the wall to move the air out of the room can also be a useful addition if you cannot expel or move the air otherwise. And be sure to leave the doors to the closet open so that the warm, moist air can move out of the space.
This is probably THE most frequently asked question about the BetterVent. The answer depends on the type of laundry you are drying and how often you are using your dryer. In our house, with two people and few loads per week, we clean the filters inside the BetterVent about every 6-10 dryer loads (or once a week).
Don't forget there is also a screen inside of your dryer that should be cleaned after each load (refer to your owner's manual). As you use your BetterVent you will know how often your filters will need to be cleaned and replaced.
If the calibrated Safety Exhaust Flap opens, you know that you have waited too long! To extend the life of your filter you can vacuum the green side of the filter multiple times before you will need to replace it with a new one.
If you have a lint roller handy you can lightly roll it over the polyester filter to remove the lint. Quick and easy! And remember, the cleaner your filters, the more energy efficient your dryer will be.
DO NOT place anything other than the recommended MERV 5 polyester filter material and provided stainless steel screen in the BetterVent.
Should you forget or neglect to clean the filters, the flap will open and remain open until maintenance is performed. This keeps your dryer from overheating and prevents damage.
If your flap is calibrated correctly it will only open when approximately 80% of the airflow is restricted. If you notice that your dryer is taking longer to dry your clothes, it may be time to change the filter.
We found that dryers exhaust air at different rates which makes it necessary for the owner to calibrate their BetterVent to suit their particular dryer.
This is an easy task. There are photos of the process under the website menu tab "calibration".
It's an "out of sight, out of mind" issue. All appliances require maintenance and the BetterVent is no exception.
Installing your BetterVent close to your dryer will make it easy to perform the simple routine maintenance that is necessary.
A shorter exhaust line will deliver a more powerful air flow through your BetterVent.
Gas dryers should ONLY be vented to the outdoors because the exhaust from a gas dryer contains carbon monoxide fumes that you do NOT want inside your home or laundry room. NEVER attempt to vent a gas dryer anywhere but outside the home.
We don't recommend that you wash the polyester filter but you can vacuum the filter numerous times before replacing it with a new one.
The cleaner the filter, the more efficiently your dryer will operate. If you notice it is taking longer for your dryer to complete a cycle, it is probably time to vacuum or replace your vent filter with a new one.
Our replacement filters offer the best airflow possible to ensure that your dryer performs at its peak efficiency. Remember to insert your BetterVent filter with the white side facing out into the room.
For best performance the manufacturer recommends that the green side face the outside when the door is closed.
Clean the filter to extend its life by lightly vacuuming or replace the filter with a new one every 8-10 dryer loads.
