Read on to learn more about how each device works and determine which one would suit best for your needs!

What is an Air Purifier?

Find out exactly how this appliance works to filter the air and learn about the pros and cons of using an air purifier in your home.

How air purifiers work

Air purifiers — also known as air cleaners, or air filtration systems — are devices that use fans to run air through a filter system in order to reduce indoor air pollution. They operate on the principle of pulling airborne particles such as pollen, dust, smoke, and other contaminants through a filter with an electric fan. This causes the pollutants to stick to the filter media and trap them inside so they can’t be released back into the room. The most common types of filters used by these devices are HEPA (High-Efficiency Particulate Air) filters which trap very small particles along with carbon filters that can remove odors and some gases from the environment.

Air purifiers come in various sizes, shapes, and designs but generally have similar features such as timers, variable speed settings for controlling noise levels, electronic particle sensors for monitoring indoor quality, auto-restart functions for when power gets interrupted or when cleaning is needed, etc. With advances in technology people now have more options like ultra-quiet models or those that even connect to wifi networks allowing users to control their device remotely from anywhere!

Pros and cons

When it comes to stifling humidity or indoor air quality, an air purifier and a dehumidifier both have their place in the home. Air purifiers work by trapping particles like dust mites, pollen, pet dander, and other allergens from the air within your home. Pros for using an air purifier include improving overall indoor air quality which can help with allergies or asthma symptoms as well as reduce airborne germs. Plus, these devices are relatively small so they don’t take up too much space.

On the other hand, dehumidifiers remove moisture from the air to prevent mold growth caused by excess humidity—which can be very beneficial in humid climates that face hot summer months with high humidity levels in particular. Dehumidifiers also come with several benefits reducing allergy symptoms due to dust mites and mildew spores and protecting furniture and clothing items from damage caused by dampness or musty odors generated when there is too much moisture present at home. However where dehumidifiers require frequent maintenance such as checking water collection containers they do consume more electricity than most standard appliances making them slightly less energy efficient than some other options on the market today

What is a Dehumidifier?

From technology to how it works and the advantages or disadvantages of using one, you’ll find all your answers on this topic by taking a closer look at what a dehumidifier is.

How dehumidifiers work

Dehumidifiers are machines designed to reduce the relative humidity in the air, making a room feel less humid and uncomfortable. The way it works is quite simple; inside the unit, there are two sets of coils—one warm and one cold—and a fan to move the air between them. As warm humid air passes over the cold coil, water vapor condenses on it and drips into a collection tray at its base. This helps to remove moisture from your home’s air before it is returned back into the room as dryer air with lower levels of humidity. Some dehumidifiers also come equipped with additional features such as an auto-drain system which allows for continuous operation without having to manually empty out the collection bucket or tray. Additionally, some models have built-in humidistats that allow you to set your desired target level of humidity so that they turn on (or off) automatically when needed.

Pros and cons

When it comes to the pros and cons of an air purifier, one of the biggest advantages is that it can improve indoor air quality. An air purifier can help reduce allergens such as dust mites, pet dander, pollen, mold spores, and other hazardous airborne particles. By removing these pollutants in your home’s circulation system, you can breathe easier knowing that the air around you is cleaner. Another bonus of using an air purifier is that limiting exposure to indoor contaminants can lead to fewer illnesses related to allergies or asthma.

However, there are a few drawbacks associated with using an air purifier as well. Depending on the system type and placement of your unit(s), frequent filter replacement may be required which can increase costs over time and generate more waste than traditional electric fans or open windows for natural ventilation systems. Additionally, some research suggests that ozone-generating electronic filters (which release small amounts of ozone gas) may have potential health implications for people who are exposed to them over long periods of time due to the increased risk of respiratory irritation symptoms.

What is the Difference Between an Air Purifier and a Dehumidifier?

Finding out what the differences are between an air purifier and a dehumidifier will help you decide which one is right for your home – so keep reading!


One of the main differences between an air purifier and a dehumidifier lies in their technology. Air purifiers are designed to filter out particles, contaminants, and odors from indoor spaces using various types of filtration systems. The most common type is the HEPA (High-Efficiency Particulate Air) filter which uses highly efficient filters made from woven fibers to trap particles down to 0.3 microns in size like dust mites, pet dander, pollen, smoke, and other allergens. Carbon pre-filters are also often utilized in many air purifiers as they absorb odors while absorbing larger particles that would otherwise clog HEPA filters and reduce their efficiency over time.

Dehumidifiers are powered by compressors or fans which draw humid air into the unit before passing it through cooling coils where condensation then occurs and moisture droplets collect at the base of the device for further disposal. These machines work by reducing humidity levels indoors without necessarily removing any contaminants from the air itself thus eliminating smaller airborne pathogens too small for both HEPA filters or carbon pre-filters to capture efficiently like mold spores, viruses, or bacteria.

 Different functions

When it comes to air purifiers, their main purpose is to filter out all kinds of pollutants from the air. This includes dust, pollen, pet dander, and other allergens as well as smoke and some forms of gases that can exist in the home environment. Air purifiers also have a built-in fan and filter which are designed to circulate the air throughout the house while trapping particles and reducing any potential health hazards.

On the other hand, dehumidifiers work by removing excess moisture from the atmosphere in order for it to be more comfortable for family members who suffer from asthma or allergies. The device does this by using a fan rather than filters so that water vapor will get pulled into an internal plastic tank where it collects before being emptied at regular intervals via automatic draining systems inside many models available today. This process also helps protect furniture, fabrics, and electronics from damage caused by too much humidity in your living space.

Benefits and drawbacks

The benefit of using an air purifier is that it can help people who are suffering from allergies, asthma, and other respiratory problems because the device effectively filters out many allergens and particles from the air. Air purifiers can also help reduce odors inside your home. An added benefit is that air purifiers may even reduce household dust levels in some cases, but will not replace regular cleaning to keep dust at bay for good.

On the downside, if used too often or incorrectly, an air purifier could be ineffective against larger airborne contaminants such as pollen grains. It is best to get a model with a high-Efficiency Particulate Arrestance (HEPA) filter which can trap smaller particles more easily than standard models. Additionally, there have been recent reports of ozone being produced by certain models which has some adverse health effects on humans and animals alike; hence advanced caution should be taken while purchasing one.

Dehumidifiers are great at helping combat issues related to moisture buildup like mold or mildew growth on walls and in basements when used correctly; reducing humidity levels prevents further damage from occurring to vulnerable structures in your house so its importance should not be overlooked especially during peak summer months here in North America where temperatures reach soaring highs leading to high levels of moisture indoors as well due to perspiration etc. On the flip side, however, too much dryness caused by dehumidification machines might cause skin irritation among other potential health hazards after prolonged exposure over a relatively long period of time.

Do I Need an Air Purifier or a Dehumidifier?

Finding out which appliance is best for your home isn’t always easy – it depends on things like the size of your space and the level of humidity you’re dealing with. Read on to learn more about when to get an air purifier or dehumidifier, and why you might need both!

When to get an air purifier

If you have breathing problems or suffer from allergies, an air purifier can help improve the air quality in your home. Air purifiers use a combination of technologies like HEPA filters, pre-filters, activated carbon, and ultraviolet light to capture pollutants. This includes dust mites, smoke particles, pollen, and pet dander that are often too small for us to even see but can cause issues with sinus congestion and wheezing if not removed from the air we breathe. Additionally, air purifiers also work to remove the odor-causing molecules, germs, and viruses that could potentially make their way into your home.

If you live close to sources of outdoor pollution such as factories or busy thoroughfares then an air purifier is recommended for improved indoor air quality. If members in your household are sensitive to foul odors caused by cigarette smoke or fumes from cooking then an air purifier might also be a good choice as they help eliminate bad smells while improving hygiene levels around the house. Finally, you should consider investing in an air purifier when someone in your family suffers from severe asthma; this will help reduce exposure triggers that can lead to coughing fits and difficulty breathing indoors.

When to get a dehumidifier

When considering whether to get an air purifier or a dehumidifier, it’s important to understand when a dehumidifier might be necessary. Typically, you’ll want a dehumidifier in spaces that tend to get extra moist like basements or laundry rooms. Signs of too much moisture include mold growth and material warping due to condensation. If your home has wood floors, rugs, and carpets that are always damp, then you may need a dehumidifier as well. Dehumidifiers can also help reduce dust mites that thrive in damp environments. Lastly, if your home has poor ventilation like small windows or no central heating/cooling system with air circulation – then these are indicators that excessive moisture is accumulating so you should consider getting a dehumidifier as well as an air purifier.

Why You Might Need an Air Purifier and a Dehumidifier

Discover what home size, space orientation, and level of humidity are the determining factors to know if you need both an air purifier and a dehumidifier!

Home size

When it comes to deciding whether you need an air purifier or a dehumidifier (or both!), the size of your living space is one of the main factors. If you live in a large house, then it’s likely that you will require multiple purifiers and/or dehumidifiers in order to adequately treat all areas. That said, even if your home is small enough that one device can take care of the entire space, there are still certain considerations worth making.

For example, if you have high ceilings and several levels in your home – plus a basement with humid conditions – then getting two devices might make more sense than just having one larger machine. Similarly, an air purifier may be necessary for your top floor due to poor ventilation or widespread pet dander contamination; but if downstairs does not experience similar issues, only using a dehumidifier can help prevent mold growth from excess moisture down below. Ultimately though, selecting the right number depends on what type of indoor environment you want to create in each part of your home!

Space orientation

When considering whether you need an air purifier or dehumidifier, the orientation of your space is important to take into account. Highly insulated spaces tend to trap moisture and can benefit from a dehumidifier because it quickly reduces air humidity levels. If your home is large enough, it’s better placed with multiple dehumidifiers in different areas since they provide spot coverage. Some rooms such as basements may be more prone to attract mold growth so having some sort of ventilation system that circulates fresh outdoor air regularly would be beneficial. Alternatively, small enclosed spaces should have both an air purifier and a dehumidifier since they work together to improve interior atmosphere quality and help maintain optimal humidity levels. Air purifiers are especially useful for apartments or smaller living spaces with few windows which usually need more intensive filtration systems without adequate airflow exchange. In these cases, powerful purification models can filter pollens, dust mites, smoke particles, and other airborne allergens creating healthier living conditions indoors.

Level of humidity

When it comes to deciding if you need an air purifier or a dehumidifier (or both), the level of humidity in your home is an important factor. Generally speaking, humid air can make allergies and asthma worse, so it’s important to manage the humidity levels within your house. High levels of humidity can encourage mold growth, and even cause condensation on windows and walls which can damage paintwork and furniture. To assess the amount of moisture in your home you can use a hygrometer which will measure the relative humidity level from 0-100%. Anything below 50% is considered comfortable while anything above 60% is too high.

A dehumidifier is designed to reduce this percentage by pulling out excessive moisture in the air as warm air passes through its filters and into its compressor where any dampness present gets extracted before being released as cooler drier air back into the room. This helps maintain a healthy atmospheric balance within your home that should strike a good balance between moist enough for comfort but dry enough to discourage mold growth – usually around 40%-50%.

Air purifiers on the other hand work by filtering out any airborne allergens like dust mites, pollen, pet dander, etc., as well as smoke particles from cooking or tobacco products that may be lingering in the atmosphere of your home. The biggest advantage with these devices is that they don’t require electricity – all they need are regular filter maintenance checks depending upon how regularly you are using them during peak times such as winter months when more people tend to stay indoors!


Keeping your home clean, fresh, and free from odors requires a little bit of effort. By understanding the roles that air purifiers and dehumidifiers play in keeping air quality good, you can make a more informed decision on whether it’s time you invest in one or both of these devices! Air purifiers help reduce levels of airborne particles while dehumidifiers remove excess moisture. It all depends on your particular space requirements – some people might need both devices to maintain optimal ambient conditions while others might only require one. No matter what type of device you get, using an air purifier and/or dehumidifier is sure to make your home a much more pleasant place to be!
