Your dehumidifier disposal options depend on whether it still works

A working dehumidifier can go to a donation center, thrift store, or online marketplace. A broken one needs to go to an appliance recycler or hazardous waste facility because dehumidifiers contain refrigerant—a chemical that damages the ozone layer if released into the air. You cannot put a dehumidifier in the trash, and most curbside recycling programs will not accept it. The route you choose depends on the unit's condition and what facilities operate in your area.

The key difference is that dehumidifiers are not like other household appliances. They hold refrigerant in sealed coils, and that refrigerant is regulated by the Environmental Protection Agency. Draining the water tank and wiping it down does not make it safe to throw away—the refrigerant stays inside the unit until a certified technician removes it.

Key Takeaways

  • Working dehumidifiers can be donated to thrift stores, Goodwill, Salvation Army, or listed on Facebook Marketplace or Craigslist, but you must be honest about their condition.
  • Broken dehumidifiers must go to an appliance recycler or hazardous waste facility because they contain refrigerant that requires certified removal.
  • Your city or county solid waste department can tell you which recyclers accept dehumidifiers and whether they charge a fee.
  • Some retailers that sell dehumidifiers, including big-box stores, offer take-back programs when you buy a replacement.
  • Never put a dehumidifier in regular trash or curbside recycling, even if it appears empty or broken.

Donating a working dehumidifier

If your dehumidifier still runs and removes moisture, donation is the fastest and most direct option. Thrift stores like Goodwill and Salvation Army accept working appliances, though policies vary by location. Call ahead to confirm they take dehumidifiers—some locations have space or safety limits. You can also list the unit on Facebook Marketplace, Craigslist, or OfferUp. Be clear about its age, any noise it makes, and whether it has been serviced recently. Many people buy used dehumidifiers for seasonal use or to test whether they need one before buying new.

If you donate through a thrift store, you may be able to drop it off without an appointment, but some require you to schedule. If you sell it online, arrange pickup or delivery with the buyer—dehumidifiers are heavy and awkward to ship. Clean the water tank and let the unit run for a few minutes before the buyer takes it, so they know it works.

Recycling a broken or non-working dehumidifier

A dehumidifier that no longer runs, leaks, makes noise, or has visible damage must be recycled through a certified appliance recycler. These facilities have the equipment and certification to safely remove and dispose of refrigerant. The process is called refrigerant recovery, and it is required by federal law before the rest of the unit can be recycled or scrapped.

To find a recycler near you, contact your city or county solid waste department and ask for appliance recycling facilities. Many areas have one or more recyclers that accept dehumidifiers. Some charge a fee (typically $15 to $50), while others accept them free if you bring them in. A few retailers, including Best Buy and some local appliance stores, also run take-back programs—if you buy a new dehumidifier from them, they may remove the old one for free or a small charge.

Retailer take-back programs

If you are buying a replacement dehumidifier, ask the retailer whether they offer haul-away or take-back service. Best Buy removes old dehumidifiers when you purchase a new one, though the service may cost $15 to $30 depending on your location. Lowe's and Home Depot sometimes offer similar programs, but policies vary by store and region. Call or visit the store's website before you buy to confirm what they offer.

Take-back programs are convenient because the retailer handles pickup or removal on delivery day. This is especially useful if your dehumidifier is large or if you do not have transportation to a recycling facility. Ask whether the fee is waived if you buy the new unit from them, or whether it applies regardless.

Hazardous waste collection events

Many cities and counties hold hazardous waste collection days one or two times per year. These events accept appliances with refrigerant, including dehumidifiers, usually for free. Check your local solid waste department's website or call their main line to find out when the next collection is scheduled and whether you need to register in advance.

Hazardous waste events are free and require no appointment at most locations, but they happen on set dates. If your dehumidifier needs to go soon and the next event is months away, a recycling facility may be faster. Some areas also run year-round drop-off centers for hazardous materials—ask your solid waste department whether yours does.

What not to do

Do not put a dehumidifier in the trash, even if it is broken or appears empty. Landfills are not equipped to handle refrigerant, and releasing it into the environment is illegal. Do not attempt to drain the refrigerant yourself—this requires specialized tools and certification, and mishandling it can cause injury or environmental damage.

Do not put a dehumidifier in curbside recycling, even if your program accepts other appliances. Most curbside programs do not have the equipment to recover refrigerant safely. If you are unsure whether your recycling program accepts dehumidifiers, call your waste management provider and ask. They will tell you the correct place to take it.

How to prepare your dehumidifier for disposal

Before you donate or recycle, drain the water tank completely and let it dry. Wipe down the exterior to remove dust and debris. If you are donating, run the unit for a few minutes to show the buyer it works. If you are taking it to a recycler, you do not need to do anything special—just bring it as is.

If the dehumidifier has a filter, you can leave it in place or remove it before disposal. Most recyclers do not care either way. If you are donating and the filter is clogged or dirty, replace it with a clean one—this makes the unit more attractive to the next user and shows you have maintained it.

Frequently Asked Questions

Can I put a dehumidifier in the trash if it is broken?

No. Dehumidifiers contain refrigerant that must be removed by a certified technician before the unit can be discarded. Putting one in the trash is illegal and harms the environment. Take it to an appliance recycler or hazardous waste facility instead.

How much does it cost to recycle a dehumidifier?

Costs vary by location and facility. Some recyclers accept dehumidifiers free, while others charge $15 to $50. Hazardous waste collection events are usually free. Call your local solid waste department or recycler to ask about fees before you bring the unit in.

Can I donate a dehumidifier that makes noise or leaks a little?

You can, but you must tell the buyer or thrift store about the problem. If you donate to a thrift store, describe the issue when you drop it off. If you sell online, mention it in the listing. Honesty protects the next user and prevents returns or complaints.

What if I cannot find a recycler near me?

Contact your city or county solid waste department—they can direct you to the nearest facility or tell you when the next hazardous waste collection event is. If you are far from a recycler, ask whether a retailer in your area runs a take-back program when you buy a new unit.

Do I need to remove the filter before recycling?

No. You can leave the filter in the unit or remove it—recyclers do not require either. If you are donating a working dehumidifier, a clean filter makes it more appealing to the next user.
