Waykar 150 Pint Dehumidifier with Pump vs Waykar CHWA Dehumidifier with Pump

Both are 150-pint Energy Star units from Waykar's CHWA line, so the real split is airflow, tank size and weight. The A model moves more air (206 CFM vs 124 CFM), holds a bigger tank (2.38 gal vs 5.5 L) and runs quieter (40 dB vs 45 dB), but it weighs about 9 lbs more. The B model is lighter, more compact and has a slightly higher owner rating, which suits people who move the unit between rooms or lift it up stairs. Buy A for a large damp basement that needs fast drying; buy B if portability and easy handling matter more.

• Choose the 150-pint pump model if you have a big, wet basement and want the strongest airflow, the largest tank and the quietest running of the two.
• Choose the CHWA compact model if you move the dehumidifier between rooms or floors and want a lighter, smaller unit with a higher owner rating.
