Eliminating mold and mildew can be an uphill battle if you don’t know how to approach it.

Mold can form on damp surfaces in less than 24 hours. So, how would you even begin to tackle such a persisting nuisance?

The number one tool you can equip yourself with is a good Air Purifier. By circulating and cleaning the air in a room, you can remove moisture, dust, and germs before it even gets a chance to form.

Not to mention the added benefit of having cleaner – healthier air to breathe in. 

Today there are an endless number of air purifiers with all the bells and whistles. To make the selection process simpler for you, we’ve compiled a list of 11 purifiers with different features and, most importantly, effectiveness for any room size you may be on the market for. 

Best Air Purifiers For Mildew & Mold 

1. GermGuardian AC4825

Kicking off our guide is the GermGuardian AC4825, which provides the efficiency of three filters in one. What’s more, the air Filter comes with a UV-C light along with its three-filter system. It has a compact and lightweight build as well if you need a filter with a smaller footprint.

Why Did We Like It?

The GermGuardian purifier is compact for the amount of filtration it offers, with the UV-C light being the key feature here. Removing viruses that other filtration systems would be unable to attack is definitely a bonus for the extra level of cleansing it offers. 

Owing to the HEPA, charcoal, and the pre-filters, nothing gets past this air purifier. Moreover, these filters can be used for 6-9 months, making them low maintenance. Even with regular cleaning every week or so, they last for a long time before needing to be replaced. 

Furthermore, the model is designed to run 24/7, so all you need to do is replace the filters twice a year and let it take care of the rest. It serves as a “set up and forget about it” option. 

Additionally, this air purifier comes at an affordable price which is always a welcoming aspect. 

What Could’ve Been Better?

This air filter from GermGuardian is not without its shortcomings, which is something to be noted before buying. First, we noticed that its replacement filters are higher in price than some other available options. There also seems to be a problem with the circuit boards of a few of these models, which might be a possible risk.

2. Winix 5300-2

The following air purifier we found is one from Winix with the latest in-air filtration technology. It has a four-stage filtration system to boot, including its very own PlasmaWave technology. Of course, its included one-year supply of replacement filters is what sets it apart.

Why Did We Like It?

Having two onboard sensors allows the purifier to tell you the air quality in real-time –  truly a no-brainer feature for air purifiers. Additionally, a sleep mode will detect when it is dark so that it automatically enters the quiet mode without a remote. Using the two features together, the Winix 5300-2 will adjust its modes based on the air quality, doing all the work for you.

There are four filters that the air passes through – a washable pre-filter, activated carbon filter, HEPA filter, and the PlasmaWave filter. It’s interesting to note that the PlasmaWave is a permanent filter that breaks down odor, allergens, and pollutants with no harmful ozone.

Furthermore, this model can cover an area of 360 sq. feet, with its HEPA filter rated to last for an entire year. And the included-year supply of filter replacements you get makes it worth the investment. 

What Could’ve Been Better?

The included air filter replacements are a nice touch; however, buying them yourself can be expensive. That said, having them last as long as they do makes them a rare purchase. 

What’s more, those who prefer having a remote along with their air purifier might get disappointed. Then again, the included auto mode has seemingly replaced the need for a remote

3. Honeywell HPA300

The Honeywell HPA300 is built for extra-large rooms while maintaining the air filtration quality of smaller filters. Backing its ability to filter air effectively, it is a highly recommended choice by allergists and doctors alike and has a 5-year warranty.

Why Did We Like It?

This air purifier is perfect for those looking to cover a larger area. It is indeed one of the best options for eliminating odors, allergens, and germs across larger areas that smaller filters may struggle with. 

Honeywell is backed by allergists and doctors, giving credit to the effectiveness of the filters. It can run 120x a day in a room as large as 465 sq. feet. All while seeing no decrease in performance or air quality. 

And with a straightforward control panel, an auto shut-off timer, filter change indicator, and light dimmer for the control panel, there is no learning curve to begin using this powerful air filter. 

From the build quality of the materials to the durability of the actual machine, you can’t go wrong if you need a purifier for large areas. A simple setup with a direct approach to operating makes it perfect for buyers in this large coverage bracket.

What Could’ve Been Better?

One downside that could be an inconvenience is that Honeywell insists on buying their brand manufactured filter replacements for effectiveness. What’s more, the pre-filter needs to be changed regularly.

It can also get deafening when set to the higher modes; otherwise, the lower settings are quieter to the point of white noise.

4. Airthereal APH26

Another all-in-one package when it comes to air purifiers – Airthereal offers a great option in their APH26 model. It has a built-in monitor that changes modes depending on the air quality. 

Additionally, the upgraded H13 HEPA filter add-on and UV light definitely help target mold formation.

Why Did We Like It? 

Using the Airthereal APH26 is a breeze both literally and figuratively. In a mere ten minutes, there was a considerable improvement in air quality. Having a smart control to switch between modes based on the air quality around the purifier allows it to be switched on and left to work. 

Now, its built-in, encased UV light will protect users from the rays while still removing airborne allergens. Working alongside this, Airthereal includes an Anion function that electrically charges dust, odors, and pollen to speed up its collection. What’s more, it does not need any replacements!

Other valuable tricks that this purifier offers include a 0-12-hour timer to tailor to any schedule, saving time and money. Furthermore, having a timer will expand the lifespan of the machine.

What Could’ve Been Better? 

Undoubtedly, this purifier is not without its share of drawbacks. After using it for a while, there was a persistent noise coming from the unit even after cleaning.

Apart from this, some may not be comfortable with the Anion setting releasing negative charges into the air to pick up allergens faster.

5. SilverOnyx Air Purifier

Another alternative comes from SilverOnyx’s air purifier. A 3-stage filtration combined with a five-fan speed setting ensures clean air circulating the room in no time. Perfect for large rooms up to 500 sq. feet, it has no problem picking up allergens.

Why Did We Like It?

Having a purifier with an H13 HEPA filter right out of the box is a comfortable investment for air improvement. Its unique round shape provides a larger surface area for more air to pass through the filters, increasing its range and effectiveness. Such is the power of the improved H13 HEPA filter. 

On top of the unit is an easy-to-see touch panel for switching between the five fan speeds. Alternatively, you may activate the auto mode to leave it to its own devices and adjust fan speeds on its own. 

More than just air filters, a UV light, and a “Negative Ion Generator” is located at the purifier base. The generator releases negative ions to draw in airborne particles faster.

What Could’ve Been Better? 

Maintenance work on the SilverOnyx AirPurifier is not the most straightforward task to handle. The P2.5 sensor compartment feels as if it could break when trying to get it open. On top of that, cleaning the sensor every month is recommended if using the purifier daily, making it a regular task.

6. Pure Enrichment PureZone Elite

Weighing in at a little below 10 pounds, the PureZone Elite is a sleek
