What’s the Difference: Air Purifier vs. Dehumidifier?

Certain factors can make your home seem less hospitable than you’d like — maybe there’s stale smell in the air every time you walk in. Or maybe it smells like the shrimp scampi you cooked for dinner…three days ago. Or maybe the air feels heavy and damp, or every time you walk through the door, you notice your eyes start watering and you’re sneezing uncontrollably. Any of these experiences could mean that your indoor air quality has been compromised. High environmental humidity, recent flooding, tobacco smoke, cooking odors, poor ventilation and living with a furry, four-legged friend can turn a normal home into an allergy and asthma trigger trap. Luckily, the latest in purification and moisture-controlling technology is here to make your life a whole lot easier — and your home a whole lot fresher!

What’s an Air Purifier?

Generally speaking, an air purifier is designed to remove contaminants from an indoor space. According to the EPA,

[Air Purifiers] are designed to remove pollutants from indoor air. They can be installed in the ductwork of most home heating, ventilating, and air-conditioning (HVAC) systems to clean the air in the entire house, or the same technology can be used in portable air cleaners that clean the air in single rooms or specific areas. Most air-cleaning devices are designed to remove particles or gases, but some destroy contaminants that pass through them.

If you don’t like the way the air in your home smells, but you don’t have the telltale musty smell of mold, then an air purifier might be ideal for your situation. Whether the stinky odors in your house are caused from cooking odors, smokers, pets or environmental factors, getting a high-quality air purifier can eliminate those odors.

Likewise, if you or someone in your family suffers from allergies or asthma, certain air purifiers are designed to help combat the very allergens that are floating in the air, exacerbating the unpleasant symptoms that are associated with breathing sensitivities.

What’s a Dehumidifier?

If you suspect that the odor in your home comes from an abundance of moisture in the air, then a dehumidifier is probably right for you. Mold has a particular smell most of us have experienced before — so you most likely will know if you have it in your home.

The first key to reducing and eliminating it is to cut it off at the source. If a water leak, roof leaks or burst pipe is allowing water into your home, it’s time to fix it and seal up the problem. After that, a dehumidifier can help dry out a particular space (like basements) or your entire home. If you live in a humid climate, or where flooding happens commonly at certain times of the year, having a device that removes moisture from their air goes a long way toward improving your indoor air quality.

Once you control and then inhibit the mold growth by cutting off its source of moisture, the smell usually goes with it — as do the mold spores that can become airborne and trigger those allergy and asthma attacks.

What if it isn’t Air Purifier vs Dehumidifier, but Air Purifier and Dehumidifier?

If you live along a coast or a naturally humid environment, but also have pets, allergies, asthma or are in proximity to a smoker or garlic-loving chef, you might consider adding both an air purifier and dehumidifier to your home for the most effective results. For example, if you have a basement where you notice a musty odor or that has flooded, adding a dehumidifier to that space and air purifiers to the upper levels of your home could be a great solution. Models work really well together  Luckily, recent technology has brought about a dual unit that functions as both a dehumidifier and an air purifier in one!
