10 Best Dehumidifier With Air Purifier 2025 in the United States

The Frigidaire Gallery 2-in-1 50-Pint Dehumidifier is a solid choice for medium to large rooms or basements, with a strong dehumidification capacity of 50 pints per day and coverage up to 4500 sq. ft. It effectively reduces moisture, which helps prevent mold and mildew. This model also improves air quality by monitoring indoor air and using a built-in filter, though it does not include advanced purification features like HEPA filtration.

One standout feature is the convenience of Wi-Fi control and compatibility with Alexa and Google Home, making it easy to manage humidity remotely. Energy efficiency is good, thanks to its Energy Star certification, helping keep electricity costs down. The 2.11-gallon tank is fairly large and offers flexible drainage options, either manual bucket emptying or continuous drain, which is great for less hassle. It also performs well in cooler temperatures, working down to 41°F.

The unit weighs 44.5 pounds, which might make moving it around a bit challenging for some users. For those seeking a reliable, energy-saving dehumidifier with smart features for large spaces and decent air quality monitoring, this unit fits well. However, if air purification is a top priority, it is important to consider whether the filter meets your specific needs since it focuses more on humidity control.

This 3-in-1 device from DINZAN combines a dehumidifier, humidifier, and air purifier, making it a versatile choice for small spaces up to about 350 sq.ft, such as bedrooms, offices, or RVs. Its dehumidification capacity is modest at 580ml per day, suitable for light moisture control but not for very damp or large areas. The air purifier uses an ion emission system and a pollen/dust filter to help reduce airborne particles and odors, which adds some improvement to indoor air quality but won’t replace a dedicated HEPA purifier.

The 800ml water tank is adequate for daily use but will require regular emptying or connection to the included drain hose for continuous operation. Noise levels are low at 45dB or less, so it can run quietly at night without disturbing sleep. Automatic humidity control is a helpful feature that switches between humidifying and dehumidifying to maintain comfortable air moisture around 40-60%. The unit is compact and easy to operate with a touchscreen and digital display, plus a mood-setting 7-color LED.

This product is a convenient multi-function appliance best suited for small rooms, offering moderate moisture control and basic air purification with quiet operation. It may not meet the needs of those requiring heavy-duty dehumidification or advanced air filtering.

The Ivation 5-in-1 Air Purifier is a strong contender for those needing air purification across large areas—up to 3,700 square feet—making it suitable for big rooms or open-plan spaces. It combines several effective technologies including HEPA, carbon, and photocatalytic filters, along with UV light and a negative ion generator, offering thorough removal of dust, allergens, germs, and odors.

The digital display, remote control, and adjustable fan speeds add convenience and allow customization based on your preferences. Despite the '5-in-1' label, this device does not function as a dehumidifier, so it won't remove moisture from the air—a key feature if humidity and mold are concerns. Additionally, the inclusion of ozone generation can aid in odor removal but may not be suitable for everyone, especially those with respiratory sensitivities; notably, this product cannot be shipped to California due to air quality regulations.

The unit is fairly compact and lightweight, making it easy to move around. This purifier excels at cleaning and deodorizing large indoor spaces but does not meet the needs of users seeking combined dehumidification and air purification in a single device.
