Waykar 158 Pint Dehumidifier for 7500 Sq.Ft Crawl Space with Remote Control | HVAC Dual Duct, With Drain Hoses, 10-90% RH, For Commercial, Basement, Whole Home, Water Damage, 5-Year Quality Coverage

I purchased a Waykar 190-pint dehumidifier in July 2025 for a large basement area. During the humid summer months, it performed very well and consistently kept moisture levels under control. The continuous drain feature worked well, and the unit removed a significant amount of water. After being shut down during the winter, the unit did not function properly when I restarted it the following spring. While that was disappointing, I contacted Waykar support and was impressed by how quickly they responded. They reviewed the issue promptly and offered a replacement under warranty. Since my original model was no longer available, they offered an upgraded replacement unit. One factor worth mentioning is that my basement is quite large, and the original unit often ran for extended periods during the summer. Because of the size of the space and my desire for additional dehumidification capacity, I purchased a second Waykar unit rather than relying on a single dehumidifier to handle the entire load. In my experience, customer service is just as important as the product itself, and Waykar has been professional, responsive, and easy to work with throughout the warranty process. Pros * Strong moisture removal performance * Continuous drain option * Easy setup and operation * Responsive customer support * Company honored the warranty without hassle Cons * Original unit developed a problem within the first year The fact that I purchased another Waykar unit while working through the warranty claim should tell you that I still had confidence in the product and the company.

### Update 2 ### Received my replacement unit within 5 days of my requesting same. Waykar Customer service kept me informed of the process every step of the way and shipment arrived right on schedule. Unit I received was brand new with a manufacturing date of March 2022. Even this was above and beyond what I expected. I thought I would have received a refurbished unit and not a brand new one. I was able to simply disconnect the cables and duct work from my old unit and put the new one in its place; and once power was turned on it took only a couple hours to be down to my desired RH setting. Unit has been working flawlessly to keep my crawl space dry once again. Thank you Waykar customer service for all your help. ***Update: After working perfectly at keeping my crawlspace dry for 20 months the unit has had issues with frost buildup at the air intake. Upon contacting Waykar customer service and explaining the problem I was experiencing, they responded overnight and requested I perform a sequence of events and take pictures to help them determine what the problem may be. Upon completing this task and provided them the information they, once again, responded overnight and offered me several options to repair/replace my defective unit. I was very happy with how quickly and congenially their customer service helped me with addressing this issue and look forward to a quick turnaround on my replacement. I would still recommend this Waykar product to anyone who is looking to combat moisture in there crawlspace. ************ The thing that sold me on this unit was the large capacity and excellent price. The specs for this unit was much higher that other manufacturers costing hundreds more. The unit arrive quickly (Amazon Prime) and in good condition. This unit was replacing another dehumidifier from another manufacturer from 5 years ago in our crawl space. Some of the big differences I liked about this new unit was the remote control panel, remote humidity sensor, and the ability to use flexible duct work to redirect the exhaust side of the dehumidifier. THe installation was relatively simple with the only effort required to remove the old unit and lift the new unit up on the mounting bracket to hang it from the floor joists under the house. With the 10M remote cable I was able to run it out of the crawlspace and onto a inside wall of the Garage for easy monitoring. The old unit was installed a good 20 ft under the house from the crawlspace entrance and had no way of knowing if it was working or not. I really liked hanging the remote humidity sensor away from the unit more close to the middle of the crawlspace. THe only additional item purchased was a 20ft 6 inch flexible duct that I connected to the exhaust on the unit and had the discharge go further back into the crawlspace, which in my opinion made for much better airflow to remove more moisture in the crawlspace. I set the humidity level at 45% and check the control panel on a regular basis, since it is easily accessible from my garage, and I have seen the level rise to as much as 48% and within a short period of time lower down to 43%. On average it fluctuates around 45% as I would have expected. So, all in all the unit performs as advertised and I would recommend to anyone needing a crawlspace dehumidifier.

After trying several consumer dehumidifiers from GE, Frigidaire, and hOmeLabs, this is the first unit that consistently reaches and maintains my target humidity level. My previous, smaller units typically failed after one season. I bought this Waykar crawlspace dehumidifier to cover a combined basement and crawlspace of about 1,600 square feet. It is large and heavy, but quieter than my previous consumer models. Because it maintains humidity so effectively, it runs much less often. Long-term reliability is still the key question. If it continues performing this well over multiple seasons, I’ll be very satisfied with the purchase.

The dehumidifier appears well built and the controls are very easy to use. The problem is that the unit very quickly overheats in a humid and warm environment. I installed it in an incubator room that needs to stay at a humidity below 20% and about 70-80 degrees to support the enclosed incubating unit. When the ambient temperature (air inflow temp) of this unit exceeds 75 degrees and 50%RH, the dehumidifier overheats and the outflow air temp rises to 105 degrees plus!. Not useful for my application. However, the biggest problem with this unit is the CUSTOMER SERVICE. You cannot speak with anyone and replies to inquiries happen by emails that are ridiculous and almost a week late! The best I can say about this unit is that it removes water from the air and has a very nice design but did not fit my application and the Customer Service is the worst I have encountered in a long long time. Further, the claim of "155 pints" (about 20 gallons)of water removed is greatly overstated. The most I got was 10 gallons on an 86 degree day with 90% RH. Update: After several back and forths via email with significant delays, customer service was willing to honor the warranty and take the unit back with a full refund. They were very understanding about how it didn't work for my application. I cannot take them up on it now as I am in the middle of hatching and added an air conditioner to handle the excessive heat. However, I upgraded the stars because they did try to accomodate me. Would have worked if we could have expedited the process by phone.

I installed the Waykar 158 Pints Commercial Dehumidifier in the attic of our 1960s house, and it has been very effective. The ducted setup was straightforward, and it runs quietly, maintaining a consistent 48% humidity even in challenging conditions. The smart controls are user-friendly and provide precise readings, as shown in the first photo with the clear display of temperature and humidity levels. The second photo highlights the solid construction and ducting setup. The feet, shown in the third photo, provide a way to adjust and have the condensate drain out. Overall, I recommend it and waykar.

Update #2 - I have now had the machine 8 months and it is getting a second error. This time "EM". It runs for a minute and shuts off. I sent an email to customer service and received no response. Interestingly enough, when I signed in to update this, my 1 star was changed to a 2. I reset it to 1, because 0 is not an option. I purchased the unit and paid to have it installed by a licensed HVAC tech. It gave a sensor error code (E4). I emailed customer service and got no response. I called customer service and nobody answered. I had to leave a call back number. I was eventually contacted by customer service via phone. All other communications were via text. The company has a US address but a lookup on the South Carolina secretary of state's website shows that it is foreign owned. The address is a ghost address used by multiple companies. So, that explains the lack of good customer service. I was first told to see if it is working and ignore the code. I was then told to let it run for 24 hours and the code will go away. I will be testing it soon and update this post. Either way, it has been a poor experience. I would not buy another one. Update - The code never went away. The company sent a new humidity sensor, which I had to install myself. That seemed to fix the problem. If there had been proper testing procedures when the product was produced, this never would have happened.

This product is exceptional. This marks the third unit I have acquired and installed within a crawlspace. The Waykar 158 Pints model consistently demonstrates high quality and operates with remarkable efficiency. The customer service team is highly responsive and effective, and I wholeheartedly endorse this product.

I have had this installed for 3 months now and I like it a lot. I use it as whole house dehumidifier and have it plumbed into my 4 ton unit which seems to cycle on and off to frequently, slightly oversized is the root cause but now I have to deal with the interior cooler box humidity issue since the blower does not stay on long enough to dry it out and that is even with the fan on continous. With this placed on a dedicated return duct in my basement blowing into the unit with the humidistat placed in the cooler box, it stays nice and dry and I can read the humidity. It has cured all the moisture and mold issues that crep up in summer months inside the unit. Now if it lasts longer than the cheap toshiba units from HD I will be more than happy.

We purchased this Waykar dehumidifier in September 2021. The unit received was in immaculate condition and has always worked well, keeping our basement dry and odor free. Must say that the device does not contain a water tank which makes it very compact. The air filter is easily cleaned with a vacuum cleaner or under water. To get it working, simply press the start function then set the desired humidity level on the touchscreen and you're done! really easy to use. This dehumidifier is mostly designed to be connected to an existing home ventilation system or can be used as is without any problem like in our basement. I should mention that a few days ago the device started showing signs of frost on the heatsink. So we contacted Waykar and Bonnie from customer service got back to us right away. Customer support is fast, efficient and above expectations. When registered within 14 days of purchase, the warranty increases from 1 year to two years. We have no hesitation in recommending this product.

I purchased this unit about a year ago. The unit is solidly build with a metal frame and metal sides. Compared to my older floor based dehumidifier this unit throws a great deal of air, making it ideal in large room or crawl spaces. The unit is meant to hang from the ceiling so I just went to a big box store and purchased some threaded rod and hung it from the rafters. It worked great and you could easily make it perfectly level. The unit came with the humidity sensor on a long cord and the control unit on a long cord. At some point I will mount the control panel outside my crawl space but for now i just leave on top of the unit. After about 11 months I has some technical issues and support, while over email, was very good. They asked detail questions and provided detail instructions on how to resolve which included pictures and at one point even a video. I am still very please with my purchase.

Used to dehumidifier a basement. After 2byears flashed an E2 code. contacted Waykar support and received a response very quickly from Penny. Excellent support received to resolve this issue.Would highly recommend Waykar 155pint dehumidifier and the Excellent customer support.

I purchased this dehumidifier about 2 years to put in my basement for the last 2 years it has ran great really hoped get the humidity and the smell out of my basement. Their online support is really friendly and helpful. I've had a stand up dehumidifier in my basement before then I upgraded to this and it really dehumidify the water it could fill up a bucket a day. It's a lot dryer in my basement I would buy this again.

I bought this dehumidifier for my 1000 sq./ft. crawlspace and it has no problem keeping the humidity at 50-55%. It's been running 24/7 since 2021. I had an E2 error with a sensor but Waykar support was fast to respond and had no issue sending me out a replacement sensor. All and all really happy with this dehumidifier and Waykar support.
