Your dehumidifier disposal options depend on its condition and what's inside it

A dehumidifier that no longer works or that you no longer need cannot go in your regular trash. The unit contains refrigerant (a pressurized chemical that cools the coils), a compressor, and other materials that require special handling. Where you take it depends on whether it still works, whether you want to reuse it, and what your local waste system accepts.

The fastest route is usually a retailer that sells dehumidifiers—many will take the old unit when you buy a new one. If that is not an option, your city or county hazardous waste facility will accept it. A few dehumidifiers can go to standard recycling, but most need the hazmat route because of the refrigerant inside.

Key Takeaways

  • Retailers that sell dehumidifiers, including big-box stores, often take old units for free or a small fee when you purchase a replacement.
  • Your city or county hazardous waste facility accepts dehumidifiers year-round and handles the refrigerant safely, though you may need to schedule a drop-off or wait for a collection event.
  • Donation to a thrift store or online marketplace works only if the dehumidifier runs and you can deliver it yourself.
  • Never put a dehumidifier in curbside trash or recycling, because the refrigerant inside is illegal to release into the air.
  • Appliance recyclers and HVAC contractors sometimes accept dehumidifiers, but call ahead to confirm they handle this type of unit.

Retailer take-back programs

Home Depot, Lowe's, and Best Buy all accept old dehumidifiers when you buy a new one. Some charge a small haul-away fee (typically $15 to $25), and some waive it if you buy the replacement from them. Call your local store or check their website to confirm the current policy, because fees and programs change by location.

This is the easiest route if you are already buying a new unit. The retailer handles the refrigerant removal and sends the dehumidifier to a licensed recycler. You do not have to transport it yourself or deal with scheduling.

City and county hazardous waste facilities

Every city and county in the United States has a hazardous waste collection program. Search "[your city] hazardous waste" or "[your county] hazardous waste" to find the facility nearest you. Many accept dehumidifiers at no cost, though a few charge a small fee.

Most facilities operate on a drop-off schedule—you bring the unit during their hours, which might be one day a week or one Saturday a month. Some larger counties run year-round collection events at multiple locations. Call ahead to confirm they accept dehumidifiers and whether you need an appointment. Bring your ID and be prepared to answer basic questions about the unit (whether it still works, whether it leaks, how long you have owned it).

Donation if the dehumidifier still works

If your dehumidifier runs and you want someone else to use it, thrift stores like Goodwill and Salvation Army sometimes accept them. Call first—not all locations take large appliances, and some require you to deliver it yourself. If they say yes, drop it off during their hours.

Online marketplaces like Facebook Marketplace, Craigslist, and Nextdoor also work if you are willing to list it and arrange pickup with a buyer. This keeps the unit out of the waste stream and puts it in someone's home. Be honest about its age and any quirks (noise, how often it needs emptying, whether it cools a small or large space).

Appliance recyclers and HVAC contractors

Some independent appliance recyclers accept dehumidifiers. Search "[your city] appliance recycler" to find one nearby. A few HVAC contractors also take dehumidifiers because they are trained to handle refrigerant. Call ahead—not all of them do, and some may charge a fee.

These are good backup options if the hazmat facility has long wait times or limited hours. Recyclers typically dismantle the unit and recover the metal, plastic, and refrigerant for reuse or safe disposal.

What not to do

Never put a dehumidifier in your curbside trash or recycling bin. The refrigerant inside is a controlled substance under the Clean Air Act, and releasing it into the air is illegal. Trash workers are not trained to handle it, and the unit will end up in a landfill where it can leak.

Do not attempt to drain the refrigerant yourself or disassemble the unit. Refrigerant requires special tools and certification to handle safely. If you open the sealed system, you risk harming yourself and the environment.

How to prepare your dehumidifier for disposal

Before you take the unit anywhere, empty the water tank or drain the hose if it is connected to a floor drain. Wipe out any standing water inside. If the dehumidifier has a filter, you can leave it in place or remove it—ask the facility or retailer what they prefer.

Do not wrap the unit in plastic or seal it in a bag. Facilities need to see it and inspect it for leaks. If the unit is leaking refrigerant (you will see oily residue around the coils or compressor), tell the facility when you arrive so they can handle it safely.

Frequently Asked Questions

Can I put my dehumidifier in the trash?

No. Dehumidifiers contain refrigerant, which is illegal to release into the air under federal law. Curbside trash and recycling programs cannot accept them. Use a hazmat facility, retailer take-back, or appliance recycler instead.

How much does it cost to dispose of a dehumidifier?

Most hazardous waste facilities accept dehumidifiers for free. Retailers may charge $15 to $25 for haul-away, though some waive the fee if you buy a replacement. Appliance recyclers vary—call ahead to ask.

Can I donate a dehumidifier to Goodwill or Salvation Army?

Some locations accept working dehumidifiers, but not all. Call your local store first. You will likely need to deliver it yourself. If they decline, a hazmat facility or online marketplace is your next option.

What if my dehumidifier is leaking?

Tell the hazmat facility or retailer when you arrive. Do not attempt to repair it or drain the refrigerant yourself. Facilities are equipped to handle leaking units safely and will dispose of the refrigerant properly.

How do I find my nearest hazardous waste facility?

Search "[your city] hazardous waste" or "[your county] hazardous waste" online. You can also call your city or county public works department. They will give you the address, hours, and whether you need an appointment.
