An air purifier is your best bet to improve indoor air quality and reduce allergens. A dehumidifier is a clear choice if you're concerned about high humidity levels and potential mold growth. However, if you live in a humid climate or the air in your home feels stifling, a dehumidifier can regulate the humidity level.
Air purifiers help people whose allergies are caused by dust mites, pollen, pet hair, and other airborne irritants. They do very little against allergies caused by the existence of mold, mildew, or dust mites, all of which are linked with excessive humidity and can be addressed by a dehumidifier.
Disadvantages of air purifiers include the cost of purchase and filter replacements and the need for regular maintenance. They may also be ineffective against certain pollutants, like larger particles or gases, depending on the filter type.
Cons of Dehumidifiers
Dehumidifiers collect water meaning they need to be regularly emptied. They also need to be regularly cleaned otherwise black mould can start to grow on the machine , which can induce a wide range of health problems including allergic reactions, lung problems and irritation.
While a humidifier can add moisture to the air, it is not designed to remove pollutants or allergens. If you want to improve the air quality in your home or office, an air purifier is a better choice.
Mold is an obvious health risk in any home, but investing in an air purifier can help limit your exposure. The best among them will ideally offer HEPA-level filtration, with this level of filtration being able to trap up to 99.97% of airborne particles down to 0.3 microns in diameter.
Can I use an air purifier and humidifier together at the same time? Air purifiers and humidifiers have very different functions, so you can use them simultaneously in the same room to add moisture and reduce unwanted particles.
Dehumidifiers are not very effective in extremely low temperatures. This is because dehumidifier coils attract water vapor, and if the temperatures drop too low — below 42 degrees Fahrenheit for example — the vapor would freeze, damaging your machine.
Dehumidifiers are great for absorbing moisture in damp houses, but they also absorb water from your laundry, which in turn means that your clothes will dry quicker. The dehumidifier then collects the water in a little container – the first time you use it, you'll be really surprised how much is in there!
In the winter, as the temperatures get colder, the air becomes dryer. You don't want to have your dehumidifier constantly running and make the air too dry. To get the best performance out of your system, only run your dehumidifier in the warmer months like the spring and summer.
Ozone-Generating Air Cleaners
One mechanism of damage results from ozone-olefin reactions, and another from ozone reacting with electron donors (such as glutathione). Inhalation of relatively small amounts of ozone can cause coughing, chest pain, throat irritation, and shortness of breath.
Medical professionals suggest prioritizing maintaining a clean home and frequently sanitizing frequently used surfaces. Air purifiers should just be an accessory to your cleaning routine, not a priority.
A dehumidifier makes the external conditions less welcoming to mold; by removing moisture, they reduce the chances of mold growth. An air purifier, however, removes mold spores from the air, making it harder for mold and mildew to create new colonies.
A cost-effective alternative to dehumidifiers
Positive Input Ventilation (PIV) is a comprehensive whole-house ventilation system that eliminates moisture and mould in your home.
If you have space for only one device and are willing to spend a considerable amount, a high-end combo unit might suffice for a small area. However, for most situations, investing in separate air purifier and dehumidifier units will provide better air quality and moisture control.

Mold stays “dormant” in the air or on surfaces even when there's no excess moisture to help it grow. If the humidity in a room increases, mold will start growing in patches on walls, clothes, and more. So, to answer your question, dehumidifiers do NOT kill mold, but they do prevent it by reducing humidity.
As long as you leave all of the internal doors open a correctly sized dehumidifier will prevent condensation and mould from appearing around the whole house.

Keep Your Dehumidifier Away from the Walls
It's easy to assume the best place to put your dehumidifier is against the wall. But it's not! Dehumidifiers suck in and expel air using vents. Blocking any of these vents can reduce your dehumidifier's effectiveness.
How Long Does It Take for a Dehumidifier to Dry Out a Room? The size of the room, the humidity level, and the extent of the water damage are some of the variables that affect how long a dehumidifier takes to dry out a room. A dehumidifier typically needs between 24 and 72 hours to completely dry out a room.
Purchase a Hygrometer
Hygrometers are widely available and the easiest way to get an accurate reading. According to Energy Star, the humidity level in your home should stay between 30-50%. A hygrometer will allow you to monitor your humidity levels, which you should do regularly to ensure consistency.
While tap water is a convenient and seemingly inexpensive option for your humidifier, its high mineral content could pose significant issues. Opting for distilled or purified water can help avoid these problems, ensuring your humidifier functions efficiently.
Place in areas with the most airflow
To get the most airflow, place your air purifier near a window, near a doorway, or on the walls where the air moves. This also helps the air purifier clean the air quicker.
