High humidity in your home is both uncomfortable and potentially dangerous to your health. Plus, your home will start to show signs of moisture in places where it doesn’t belong.

Look no further than an air purifier with a dehumidifier – a convenient combination of two essential household appliances that restore your living conditions.

Benefits of Air Purifier with Dehumidifier

If you live in a wet climate, you know the impact that humidity and moisture in the air can have.

From sweating to discomfort to breathing difficulties, nobody wants to experience humidity – and neither does your home.

High humidity contributes to the development of bacteria, mold, and dust mites that degrades the air quality in your home and introduces musty odors that are hard to remove. 

On top of making your home uncomfortable and unhealthy, humidity can also cause wooden floors or windowsills to warp by creating window condensation, stains on walls and ceilings, rot in the structure of your home, and increased pest presence that causes trouble for any homeowner or tenant.

With a combination of air purifiers and dehumidifiers, you can tackle many of these problems with a single device.

The dehumidifier will help to remove excess moisture from the air, while the air filter works to remove particles like dust, dirt, and mold from the air.

These features allow you to address any existing conditions while preventing future problems with your home’s humidity and air quality.

Air Purifier with Dehumidifier: What to Look For?

Rate of Dehumidification

When it comes to making your home more comfortable, how quickly an air purifier and dehumidifier can remove moisture from the air is one of the most important factors to consider.

If the device struggles to remove large quantities of moisture each day, it may not be able to keep up with the source of the humidity.

You might be able to stop the problem from getting worse, but it will be hard to return your air quality to a comfortable standard without the right power.

In general, it’s better to get an air purifier with a dehumidifier that has a higher capacity for removing moisture from the air.

This is especially true for larger rooms or rooms with poor airflow that would limit the unit’s ability to effectively address all of the air. 

As a rule, aim to maintain humidity between 30-50% for the best results.

Tank Capacity

dehumidifier water tank

When your air purifier’s dehumidifier removes moisture from the air with its refrigerated coils, the condensation that forms needs somewhere to go.

Fortunately, dehumidifier systems have a reservoir or tank that’s placed under the coils to collect the condensation, allowing it to be removed from the air and disposed of.

If you want to go longer between emptying the tank, choose a model that has a larger tank.

You’ll also want to keep an eye out for an auto shut-off feature that stops the water from overflowing if you’re not able to get a large-capacity tank.

Effective Range

Similar to the dehumidifier’s rate of dehumidification, your air purifier with dehumidifier also has an effective range that tells you how large of a room it can effectively support.

This figure applies to both functions as they’re both dependent on how strong the fan that pulls air into the filter and refrigerator coils is.

A stronger fan means it can move more air, allowing it to remove allergens and moisture more efficiently.

Try to find a model with an effective range that matches or exceeds the size of your room to ensure that all air is treated.

You may even want to consider two air purifier and dehumidifier combinations for larger or oddly-shaped rooms with interrupted airflow.

Air Filter Type

filter type - best air puifier with dehumidifier

There is a wide range of allergens, pollutants, and particles that can be present in your home. This is especially true for homes with high humidity which makes them more susceptible to mold growth.

An air purifier’s filter allows it to treat the air it draws through the fibers and layers of the filter to remove as many particles as possible so that your air quality is higher.

The effectiveness of your filter, however, depends on the type and grade of the filter you’re using in your air purifier with a dehumidifier.

HEPA filters are the best option to look for.

These disposable air filters often contain multiple layers of different filtrating materials to comprehensively remove all the pollutants from a room’s air.

Dust, dirt, pollen, odors, and germs can be addressed with a high-quality filter to lessen the impacts of humidity and help with allergies to make your home more comfortable.

Look for H12 to H14 HEPA filters for the best results.

These grades of filter can address between 99.5% to 99.995% of particles 0.3 microns or smaller leading to the efficient removal of most airborne allergens.

They should also include an activated carbon layer to remove odors so that you can get rid of the musty smell humidity brings.

Some dehumidifiers with additional air purifiers feature lower-grade HEPA filters or washable filters that can be reused for extended periods of time.

While these filters are able to remove larger particles from the air, they often lack the necessary components to remove smaller particles like dust or mold and cannot address odors, leading to lower air quality than HEPA filters.

Auto Shut Off

One of the most important features a dehumidifier can have is the ability to turn the unit off automatically once the tank is full.

Using a sensor, the unit itself can detect when the water level reaches a certain position and turns itself off.

Many dehumidifiers have this essential feature due to the risk of overflowing tanks damaging units, causing damage to your home, and reintroducing humidity into the air.

If your unit doesn’t have this feature, you’ll need to keep an eye on your air purifier with a dehumidifier to ensure you’re not experiencing harmful leaks.

Extra Features

During your search for an air purifier with a dehumidifier, you’ll come across a few extra features that can help distinguish which is the best choice for you.

A timer is a convenient feature that’s included in some models.

With a timer, you can set the model to operate for a certain period of time – like an overnight period – and then have it turn itself off after that period of time to help save on electricity or maintain ideal humidity levels.

A drainage hose is another feature you’ll often see on larger models.

This feature allows you to bypass the tank’s storage limitations and directly drain the water elsewhere so that you don’t have to monitor the tank’s fullness.

Some models will also feature an additional air purifier device, such as an ionizer, to help better deal with airborne particles that degrade the air quality.

These are secondary to the HEPA filter but can be a convenient addition to your filtration system.

Air Purifier with Dehumidifier FAQs

How Big Should My Water Tank Be?

Generally, you want to find as large of a water tank as possible to allow for uninterrupted usage.

Many units will feature a liter or larger, but compared to units that are strictly dehumidifiers, air purifier and dehumidifier combinations have less tank space, so be ready to dump the water (or set up the hose feature).

What Kind of Filter Should I Look For?

If you want to effectively filter the air in addition to removing humidity, look for combination units that feature a HEPA filter that is H12 or higher in grade so that mold, dust, dirt, and other airborne particles can be removed.

An activated carbon layer within the HEPA filter is also beneficial for removing the musty odor that high humidity can leave in your home.

What’s A Good Rate of Dehumidification?

All of our recommendations remove moisture at a rate of approximately 600 ml per day or more, depending on the speed setting used.

A higher rate of dehumidification allows the unit to better regulate the humidity in your room, so aim for 750 ml to 1L per day when possible. 

Will An Air Purifier With A Dehumidifier Remove Musty Smells?

An air purifier with a dehumidifier will not remove a musty smell from your home unless your filter includes an activated carbon layer that adsorbs the odors when the unit pulls air through the filter.

Reusable or washable filters will not be able to achieve this, so look for multi-stage HEPA filters over H12 in rating.

What Should My Home’s Humidity Level Be?

The ideal humidity for your home should fall between 30% to 50% for optimal breathing conditions and comfort.

Air Purifier With Dehumidifier: Final Thoughts

An air purifier with a dehumidifier is the perfect way to comprehensively address your home’s humidity — and the air quality decrease that humid conditions can cause.

These 2-in-1 machines can save you time and money while making your room more hospitable in as little as a few hours.

Be sure to find a model with a large tank or connection for a drain tube so that you can avoid having to regularly check on the machine.

Auto shut-off functionality is also essential to protect from damaging your home or unit when the tank gets too full, and a timer can make it easy to set it and forget it.

You’ll also want to ensure your model uses a high-grade HEPA filter and verify the unit’s range so that you can be sure all the air can be addressed effectively for the best results.
