Waykar CHWA80B 80-pint ENERGY STAR dehumidifier review

Waykar’s CHWA80B is the 80-pint, auto-swing member of the CHWA-B portable dehumidifier family. Its 80-pint headline is a hot, very humid maximum, not a promise for a typical basement: the current ENERGY STAR record gives a 24.91-pint/day Appendix X1 rating, and the manual rounds the 65°F/60% RH result to 24.9. That makes the exact test condition as important as the model name when deciding whether this is enough capacity.

This assessment uses Waykar’s CHWA-B product page and selected CHWA80B offer, the manual naming CHWA80B, CHWA120B, CHWA150B and CHWA150PB, and the EPA record for CHWA80B. The certification data is not a room test.

Waykar uses this CHWA-B cabinet view across its size selector. Check the selected model code for the capacity and drainage setup that fits your space.

Compare the 80-pint label with the standardized rating

The manual lists 24.9 pints/day at 65°F and 60% relative humidity, 33.7 at 80°F/60% RH, 50.8 at 86°F/80% RH, and 80 only at 95°F/90% RH. The EPA figure of 24.91 agrees with the manual’s rounded cool-condition rating. Its 1.90 L/kWh integrated energy factor and 260 kWh/year are standardized program figures; they are useful for comparing certified records, not a prediction of your electric bill. The current exact record lists ENERGY STAR certification and Most Efficient status. It also says Connected Capable: No, so this is not a choice for a required app connection.

Waykar’s page gives a 5,000-square-foot coverage estimate, but a square-foot claim cannot account for outdoor moisture, leaks, open doors, temperature, or how quickly the room gains water. If you have a verified minimum of 25 pints/day under the site’s standardized capacity filter, this model falls just short at 24.91. A higher capacity selection should be based on the rating and conditions you intend to compare, not on matching the 80-pint hot-test headline to another model’s different test.

What auto-swing changes—and what it does not

The CHWA80B’s outlet can oscillate side to side. The manual says to start or stop the louvers with the Auto Swing button and not to move them by hand. This is a real convenience distinction from fixed-vent CHWA-A models such as CHWA80A: it changes how the discharge is directed around the room, not the machine’s moisture-removal rating. If you prefer a steady direction or want a simpler outlet, compare the fixed-vent version rather than assuming the auto-swing option is necessary.

The exact CHWA80B is not a pump model. Its practical water choices are the fitted tank or a gravity hose to a lower drain. The manual’s 1.45-gallon tank stops the compressor when full; the tank must be emptied and seated correctly before normal operation resumes. The product page lists a 3.3-foot gravity hose, and the manual requires a smooth downward route with the drain outlet at least 3.94 inches below the drain port. A hose that kinks, rises, or ends too high can back water into the tank. Neither the exact manual nor page establishes bucketless operation.

Check the installation space before choosing

The manual recommends at least 43 square feet of operating area, 18 inches of clearance around the appliance, and a 41°F–95°F operating range. It documents three manual fan speeds, auto-defrost, a 24-hour timer, and a 30%–80% humidity target in five-point steps. The removable filter is at the rear and needs regular cleaning. These are more useful planning details than a vague “large room” label: confirm there is room for airflow, a grounded outlet, and somewhere for either the tank or the short gravity hose to work.

Who should shortlist the CHWA80B?

Consider it when you want an auto-swing outlet, a standard-condition rating around 25 pints/day, and either tank collection or a short downhill drain. It is the smallest CHWA-B capacity, but its one-and-a-half-gallon tank still needs attention if it fills often. For a larger moisture load, CHWA120B raises the standardized rating to 35.20 pints/day while keeping the same 1.45-gallon tank; CHWA150B has a 49.52-pint rating and a larger tank. None of those non-pump B models can substitute for an upward pump route.

Skip this exact model if your installation requires a built-in pump, verified app control, or a 25-pint/day minimum under the standardized rating used by the finder. If an auto-swing louver is essential, choose the B code rather than a fixed-vent sibling. If it is not, compare the CHWA80A on its own fixed-vent evidence. For any of these variants, verify the code on the offer: the selected model, not the shared family photograph, determines the rating and water path.
