Top 7 All-in-One Air Purifiers and Dehumidifiers for 2025

Air purifiers and dehumidifiers offer the perfect combo. They both work at pulling things out of the air to make it fresher for you. Air purifiers use a filter to pull allergens and dust out of the air, while dehumidifiers pull moisture out of the air, which can cause mould growth. They’re both great appliances on their own but, together, they’re even better. In 2025, combination units have become increasingly popular for their ability to tackle multiple indoor air quality issues in one device, saving space and reducing clutter.

Why Choose an All-in-One Air Purifier and Dehumidifier?

The Afloia Q10 seamlessly purifies and dehumidifies, offering cleaner air and optimal humidity control in one sleek device. Truly transformative for indoor spaces. These 2-in-1 devices are particularly great for small spaces, helping to reduce clutter by eliminating the need for separate appliances while delivering healthier air year-round. If you’re dealing with dry, dirty air in the home, you’ll save money and space by not having two separate devices, plus our tests find that many combo units do both jobs effectively.

Testing Scenarios and Performance

We tested home dehumidifiers to find the most reliable picks including the best dehumidifiers for basements, small dehumidifiers and budget dehumidifiers. Our team in the Home Improvement & Outdoor Lab at the Good Housekeeping Institute tested more than a dozen dehumidifiers across every size category. Job number one for any dehumidifier is pulling moisture from humid indoor air, quickly and efficiently. We measured how efficient the units were by measuring their ability to reduce relative humidity (RH) from a sticky 80% at 70 degrees Fahrenheit to a comfortable 50%. All units performed similarly; reducing the humidity to a comfortable 50% without issue within the four-hour test period, set to their highest speed fan settings.
For air purification, we conduct smoke tests to see how the air purifier handles heavy pollution. We burn a handful of matches and several incense sticks, then run the appliance for half an hour on the highest fan setting (and an auto mode, if applicable). We make note of changes to air quality readings after 15 and 30 minutes and calculate the percentage of particulate matter removed by the air purifier. The Afloia Q10, for instance, reduced particulate matter by 90% in 30 minutes, outperforming some standalone purifiers.

Buying Guide for All-in-One Air Purifiers and Dehumidifiers

When investing in an air purifier and dehumidifier combo, there are certain essential features that should be a given. These core elements ensure the unit is efficient, reliable, and worth your money.

• Moisture Extraction Rate: A high-performance unit should remove at least 10–25 litres of moisture per day, depending on room size and humidity levels.
• HEPA Filtration: A quality combination air purifier should include at least an H13 HEPA filter, capable of capturing 99.5% of airborne particles such as dust, pollen, and allergens.
• Energy Efficiency: The device should be optimised for low power consumption to reduce electricity costs, with models ideally using no more than 300W.
• Water Tank Capacity: The dehumidifier should have at least a 4L tank for effective operation, along with an automatic shutoff to prevent overflow.
• Portability: Castor wheels and a carry handle should be included to easily move the unit between rooms.
• Multi-Room Suitability: The device should function effectively in different spaces, including bedrooms, kitchens, bathrooms, and basements.

Maintenance Tips

• Keep the Device in an Optimal Location: Placement matters! For air purifiers, keep them at least a few feet away from walls or large furniture to allow for proper airflow. Dehumidifiers need space too, especially around their air intake and exhaust.
• Check the Humidity Levels: For dehumidifiers, it’s crucial to monitor the room’s humidity. Aim for levels between 30% to 50%. Some units come with built-in hygrometers, but having a separate one can be beneficial to double-check.
• Don’t Overwork the Device: Running your device 24/7 can wear it out faster. While some situations might require continuous operation, giving it a break now and then can extend its lifespan.
• Inspect the Power Cord Regularly: This is an easy step to overlook, but a damaged power cord can be a safety hazard. Ensure it’s not frayed or damaged. If you spot an issue, replace the cord or consult the manufacturer.

Frequently Asked Questions (FAQ)

1. Can an all-in-one air purifier and dehumidifier replace separate units?

Yes, for most households, these combo units effectively handle both air purification and dehumidification, especially in small to medium-sized spaces. However, for extreme humidity or heavy pollution, standalone units might offer more specialized performance.

2. How often should I replace the filters?

HEPA filters typically need replacement every 6-12 months, depending on usage and air quality. Check the manufacturer’s guidelines, and consider washable pre-filters to reduce costs.

3. Are these units noisy?

Most models, like the MeacoDry Arete One, operate at 30-35 dB, similar to a whisper, making them suitable for bedrooms or offices. Always check the noise level specs before purchasing.

4. What room size is best for these combo units?

Units like the Devola 25L suit rooms up to 600-800 square feet, while smaller models like the DR.PREPARE are ideal for spaces under 200 square feet. Match the unit’s capacity to your room size for optimal performance.

5. Do these devices help with allergies?

Yes, the HEPA filters in these units capture allergens like dust, pollen, and pet dander, significantly reducing allergy symptoms. Models with activated carbon filters also tackle odors and VOCs.
