It’s essential to keep your home safe. Not only by investing in the best security system. But by maintaining the ideal humidity level and reducing airborne pollutants. The only way to do both using a single device is a dehumidifier and air purifier combo.
According to the EPA, the recommended indoor relative humidity is between 30% and 60%. Airborne particles such as dust, pollen, pet dander, smoke, VOCs, odors from pets and households are harmful. They trigger asthma, allergies, and other respiratory issues. Mold and mildew are toxic too, and they can exacerbate respiratory problems.
To remove triggers of asthma and allergies, buy the best dehumidifier and air purifier combo. Here are 7 we found for you.

How Dehumidifier and Air Purifier Combo Works?
There are usually three types of dehumidifiers:
1. Peltier / Thermoelectric Dehumidifier
The small-sized dehumidifiers use static Peltier (thermoelectric) technology to dry the air. Basically, air passes over a colder side of the heat sink. The moisture condenses into water droplets and drips into a water tank or pan.
This type of dehumidifier works best in warm and humid conditions.
2. Compressor / Refrigerant Dehumidifier
The high-capacity dehumidifiers use refrigerants and a compressor like refrigerators. When the humid air passes through the cold evaporator coil and fins, the moisture condensed and drips into the reservoir.
Compressor dehumidifier can’t also work in lower temperatures (normally below 20 degrees celsius). At this level, frost starts to accumulate on the evaporator coils.
3. Desiccant / Sorbent Dehumidifiers
Unlike the Peltier and Compressor dehumidifiers, the Desiccant dehumidifiers can operate in almost any weather condition. This type of dehumidifier use desiccant (sorbent) material such as silica gel to absorb moisture from the air. After absorbing the moisture into its rotating disk, a hot stream of air removes the moisture from the rotor.
Air Filters in Dehumidifiers
Dehumidifiers also use physical filters to trap airborne pollutants such as dust, lints, pet dander, and pollen. Some models have a permanent washable filter, while others have a 2 or 3-in-1 filtration system. As the air passes through the filters, the contaminants get trapped, and the machine delivers clean air to the room.
Does a Dehumidifier Cool a Room?
No, a dehumidifier doesn’t cool a room. Because like an air conditioner, there are no heat pumping mechanisms in dehumidifiers to remove the heat out of the room. Both the cold and hot coil stays in the same place, and they canceled each other. So the room temperature remains unchanged.
However, the compressor motor releases some heat energy which might increase the room temperature slightly.
On the other hand, desiccant dehumidifiers purposefully use heating elements in the dehumidification process. This type of dehumidifier increases room temperature.
| Dehumidifier Technology | Cool or Heat the Room? | Moisture Removal Efficiency |
|---|---|---|
| Peltier / Thermoelectric | No temperature changes. | Low |
| Compressor /Refrigerant | The compressor generates some heat which increases the room temperature slightly. | Medium |
| Desiccant / Sorbents | The heating elements increase the room temperature remarkably. | High |
