Aside from that, this air purifier works quietly or just 44 dB. It’s also ENERGY STAR-certified and only consumes 64 watts. You can use the Eco Mode to save more electricity when the basement air isn’t too polluted.
Unfortunately, this specific unit isn’t WiFi-powered, unlike the Airmega 400S and 300S. Still, it has an auto-sleep mode, filter lifetime indicator, and three manual fan speeds. You can also set the timer in three durations.
Overall, this is a powerful and aesthetic air purifier. However, the charcoal filter replacements are a bit pricey, which can be intimidating for those on a budget. But if you want efficient air cleaning, this is well worth the splurge.
How to choose the best air purifier for mold in basement
If this is your first time buying an air purifier, choosing from hundreds of options in the market can be challenging. To make it easier, here are some of the aspects to consider:
✔️Capacity and room size
The very first thing you should consider is the capacity of the air purifier against the size of your basement. For this part, we have to look at two things: CADR and floor area.
CADR stands for clean air delivery rate, which refers to how fast an air purifier can filter pollutants per hour. Most units are measured against pollen, dust, and smoke since these are the ones often in indoor settings.
In general, the higher the CADR, the better for highly polluted basements. There’s no industry standard as to what CADR fits a specific floor area. Still, most manufacturers will provide a CADR value alongside the maximum recommended floor area where you can use the unit.
For example, an air purifier with a CADR of 200 will perform well in a floor area not larger than 300 sq. ft. Overall, the CADR value and floor area directly proportional.
Take note that CADRs are tested on an 8-feet ceiling height, which would not be an issue for most basements.
For large basements with a bad case of molds, a high-powered air purifier is the best choice. The only downside here is the price and noise level. Still, those two aspects are tolerable if we’re going to prioritize function.
Once you’ve figured out the right CADR for your basement, the next thing to check is the filtration stages of an air purifier. Take note that air purifiers come in different filtration systems, which will affect how well they can trap mold spores.
The following are the ideal filters to use for an air purifier in your basement:
- True HEPA filter. High-Efficiency Particulate Air (HEPA) filters can remove up to 99.97% of all airborne particles. It can also trap irritants that are as small as 0.3 microns. This filter is very effective in removing airborne mold spores in your basement.
- Activated carbon filter. This filter helps neutralize malodors brought by molds and other irritants. It’s a porous and pure material that can cleanse the air while giving an added mold trap.
- Activated charcoal filter. Similar to carbon filters, activated charcoal will remove bad odors and gasses in your basement. It’s a natural material that can trap impurities and allergens.
- UV filters. This filter disinfects the air to kill airborne viruses and bacteria. It’s often used in hospitals and laboratories to prevent contamination.
These are just a few of the widely used filters in air purifier products. Many manufacturers use their proprietary filtration systems to improve the functions of their air purifiers.
Whatever filter you choose, make sure that replacements are easily available. This will save you from the possibility of having to buy a new air purifier.
Many buyers consider the noise level of an air purifier as a paramount concern. But in my opinion, this is a matter of trade-offs if you want to enjoy efficiency.
The thing with air purifiers is it gets noisier the more it becomes powerful. This is highly understandable due to the larger motor that a high-CADR unit uses. The good thing is that many models have adjustable speeds that will allow you to control the noise level to some extent.
Since the air purifier will be used in the basement, I don’t think noise levels will be a bigger problem. Unless you’re planning to live in your basement, you should look for a quieter unit to use.
✔️Controls and indicators
Make sure that the air purifier you’re going to buy has adjustable speeds. This will let you customize the filtration and tone down the noise. Overall, I try to look for the following features:
- Filter indicator. This will light up once you need to replace or wash the filters.
- Air sensor. Often found on higher-priced air purifiers, air sensors detect the level of pollutants in the room. It will then direct the air purifier to adjust its filtration level accordingly.
- Night light. Air purifiers are often built with ambient night lights to keep them low-key at night. It’s not really a must-have, but still a good feature to have at your disposal.
- Smart connections. Premium air purifiers are sometimes equipped with smart connectivity. This will let you control the unit through your mobile phone. It lets you monitor the airspeed, air quality, and other features without having to go back and forth to your basement.
You can find other features that will make your life easier when using the air purifier. Not all of it is necessary, but it will make a big difference if you’re into convenience.
Always look for air purifiers that are certified to be ozone-free. Ozone is a harmful substance, which can cause serious problems due to long exposure.
In the past, air purifiers use ozone to kill bacteria and viruses. While it’s very effective, it also recorded side effects to users.
To answer the need for a safer alternative, air purifier manufacturers switched to ultraviolet technology. It does well in neutralizing pathogens in the air without producing any ozone.
✔️With or without remote controls
You can also choose between remote-controlled or manual air purifiers. Both work well, but remote-powered ones are convenient, especially for basement purposes. It can be tiring to go back and forth in your basement just to change the airspeed or turn off the unit.
✔️Price and warranty
Lastly, you should consider the price and warranty of the unit you’re going to buy.
If you need a powerful air purifier for your basement, I suggest investing in a top-dollar unit. Just make sure that it’s backed by a decent warranty in case manufacturing defects surface.
Added tips to eliminate molds in your basement
Aside from using a powerful air purifier, the following tips will help maintain a mold-free basement:
- Prevent condensation. Condensation often occurs on basement windows and doors as this is where the indoor and outdoor air meets. You should manage this to prevent moisture from building up in your basement, which can cause mold growth.
- Keep your vents clean. It’s best to schedule vent cleaning regularly. This will prevent moisture and mold spores from harboring on your HVAC system. I suggest getting a contract with a local HVAC contractor for periodic cleaning at a low cost.
- Fix leaks right away. When it comes to molds, you have to be proactive when a leak occurs. You have to prevent water damage and moisture from seeping through the walls. It’s best to hire a professional water damage remediator if the damage is already extensive.
- Avoid storing damp items. Many of us are guilty of dumping junk into our basements. If you’re using your basement as a storage area, make sure that the items are not wet or damp. Remember, you have to avoid any source of moisture.
- Check your gutters. Always ensure that your downspouts and gutters flow away from your house’s foundation. This will prevent your basement from absorbing moisture.
- Insulate your pipes. You should insulate all the pipes running through the basement using fiberglass or pipe sleeves. This will prevent condensation, especially during the winter season.
- Avoid carpeting. If your home had a massive mold problem before, it’s probably best to skip carpeting for your basement. I suggest sticking to washable rugs that you can easily take outdoors.
- Do not bring plants into the basement. While potted plants may help spruce up your basement, it also brings unnecessary moisture for molds to grow. No matter what plant you’re thinking of, it’s best to keep it in your living room and other areas with better ventilation.
