When you consider you’re buying four appliances in one, the price is unbeatable. It’s an enthusiast’s dream for maximizing utility in a small living space.
The Honest Truth
While it isn’t the most powerful dehumidifier on the list, its ability to pivot from a dryer to a humidifier makes it the best dehumidifier with air purifier for people who live in climates with volatile weather.
Expert Comparison Insights
Having run these machines side-by-side in my workshop, the differences become clear when you look at your specific needs. The KeepGlad and Frizzlife models are the heavy hitters regarding water removal, utilizing dual-semiconductor tech to outperform the more basic models. However, the Tenergy Sorbi is the only one in this group featuring a True HEPA filter, making it the superior choice if your primary goal is removing microscopic allergens like pollen and pet dander.
The 3-in-1 Combo stands alone in its versatility, but it has the lowest moisture removal rate of the group at 580ml/day. If you are dealing with a serious moisture issue, the KeepGlad’s 1200ml/day capacity is nearly double the performance. On the other hand, the Frizzlife’s 135oz tank is nearly four times larger than the Tenergy’s tank, meaning you can go days without thinking about maintenance.
Final Verdict: The Rankings
After weeks of testing and monitoring these units, here is how I rank them for different home scenarios:
- Best Overall: KeepGlad Dehumidifier
This unit takes the top spot because it balances high moisture removal (40oz) with the most user-friendly features. The inclusion of a drain hose and a clear digital display makes it the most “pro-level” experience of the bunch. - Best Value: Frizzlife DH80
For those who want maximum capacity without breaking the bank, the Frizzlife is incredible. The massive 135oz tank and the added negative ion function provide a high-end feel for a mid-range price. - Best for Beginners: Tenergy Sorbi

Expert Buying Guide
1. Prioritize Your Primary Need
When I’m looking for a hybrid machine, I always ask: Am I more worried about the mold or the sneezing?
* If you have allergies, look for a unit with a HEPA filter (like the Tenergy).
* If you have damp walls or musty smells, look for a high daily removal rate (like the KeepGlad).
2. Check the Tank-to-Performance Ratio
There is nothing more annoying than a powerful dehumidifier with a tiny tank. I recommend looking for a tank that is at least 2x the daily removal rate if you don’t plan on using a drain hose. This ensures you only have to empty it once every 48 hours rather than twice a day.
3. Noise and Placement
In my experience, semiconductor (Peltier) units are much quieter than compressor units. If you are placing the unit in a bedroom, ensure it is rated under 40dB. Also, check for a “Sleep Mode” that dims the lights, as many of these modern units have bright LEDs that can be distracting at night.
Common Questions About Best Dehumidifier with Air Purifier
What Is the Best Dehumidifier with Air Purifier for Small Bedrooms?
For small bedrooms, the Tenergy Sorbi is often the top choice because it combines True HEPA filtration with a whisper-quiet Peltier cooling system. It effectively dries the air while removing 99.97% of dust, ensuring you breathe clean air while you sleep.
Can these units remove mold spores from the air?
Yes, models equipped with True HEPA filters or negative ion generators are specifically designed to capture or neutralize airborne mold spores. While the dehumidifier prevents new mold from growing by lowering humidity, the purifier side cleans up the existing spores.
Do I need to replace the filters regularly?
Absolutely. In my testing, I’ve found that a HEPA filter usually lasts 3 to 6 months depending on the dust levels in your home. Some units, like the KeepGlad, use washable pre-filters which save money, but for true purification, you’ll eventually need to swap out the internal media.
How much electricity do these hybrid machines use?
Most of the models I reviewed use between 45W and 90W. To put that in perspective, that’s about the same as a traditional incandescent light bulb or a large laptop. They are much more energy-efficient than full-sized basement dehumidifiers.
Can I use the purification function without dehumidifying?
In many multi-functional units, the air filtration happens automatically as long as the fan is running. However, some advanced models allow you to toggle the dehumidification chip off while keeping the fan and filter active, which is great for days when the humidity is already perfect.
