Air Purifiers For Large Rooms Buying Guide

Air Purifiers For Large Rooms Buying Guide

Reasons Consumers Need Air Purifiers For Large Rooms

Air Pollution: With the majority of hours in a day spent indoors, the quality of air ingested is one of the most important factors of overall health. While certain indoor air pollutants are unavoidable, some pollutants can be controlled in the home, from cigarette smoke to cleaning products. A quality air purifier acts as a convenient at-home solution, using internal filters to collect toxins and release new, clean air.

Pet Dander: When pet dander accumulates in the home, it can cause reactions from those living inside, ranging from mild to severe. Allowing dander and pet proteins to accumulate can compromise the integrity of the air circulating in the home. Finding the best air purifier for allergies is the first step to minimizing the health-related impacts of pet fur and dander indoors, and ensuring pet owners can enjoy spending time with their animals without risking rashes, watery eyes, and congestion.

Dust Mites: Dust mites can be challenging to eliminate since they are minute and not easily detectable in many homes. They can trigger asthma or allergies in homeowners and their families since they can live in bedding, upholstered furniture, and carpets. While the majority of homes are susceptible to dust mites, today’s professional air purifiers are designed to relieve these harmful allergens.

Mold Spores: Mold spores are made up of fungi that produce microscopic cells and are one of the most harmful toxins families can face in their homes. Those exposed to mold are at risk of respiratory problems, sinus congestion, and skin irritations. Children and the elderly are especially at risk. To help combat this toxin, consumers are looking for the best air purifiers for large rooms to help trap allergens and harmful airborne particles, in exchange for clean air that protects them and their families.

Top Features of Air Purifiers For Large Rooms

Top Features of Air Purifiers For Large Rooms

Noise Level: No matter which room you decide to designate to your new air purifier, noise reduction is an important feature to consider since a unit that is too loud can impact your ability to relax and feel comfortable in your home. The best quiet air purifier for large rooms should offer multiple volume settings for added convenience.

CADR Rating: To understand the full capabilities of an air purifier, it’s important to consider its CADR rating. This rating determines how quickly a device can eliminate harmful pollutants from the air in its designated room. This particular metric can help you determine which unit offers the best value for your money and optimal protection for your family.

Air Filters: Without quality filters, air purifiers cannot adequately protect households from dust, allergens, and airborne viruses. There are seven primary types of filters available but the most common is HEPA, which is a pleated mechanical filter designed to remove approximately 99 percent of all airborne toxins.

Air Changes Per Hour: When it comes to the performance of an air purifier for large rooms, the total ACH — air changes per hour — is an important factor for consumers to consider. A device’s ACH tells users how many times per hour air is filtered and is important to consider when comparing different brands. The higher your unit’s ACH is, the more clean air is circulated in your room for maximum protection. 

Frequently Asked Questions About Air Purifiers For Large Rooms

What is an air purifier? 

An air purifier is a piece of equipment for the home that can purify the air through sanitization. The best air purifiers for small to large rooms are designed to capture allergens, pollutants and toxins from the air, protecting you and your family.

How does an air purifier work? 

Air purifiers are designed with a filter, or potentially multiple filters, and an internal fan to capture and circulate air. While the air is circulating inside, clean air is released back into the room, helping to purify the space and protect those in the home from harmful allergens, toxins, and pollutants.

In most cases, the best air purifiers for large rooms and allergies have filters that are made of fibre or paper and require regular cleaning and maintenance to ensure your air purifier can function properly and keep everyone indoors safe.

Are air purifiers safe for pets?

Pet owners can rejoice because there are plenty of air purifiers on the market that are completely safe to be around animals. Like humans, animals require clean air to maintain a healthy life, which can be challenging when there are harmful pollutants in the air.

While the device offers numerous benefits to homeowners and their pets, it’s also important to note that its external chords cause harm to animals if they become trapped or chew on the chord itself. To ensure your pet can safely roam around the home and enjoy the benefits of your air purifier, be sure to keep it in the corner or, if it’s portable, out of reach completely.

Air cleaner vs. Air purifier

While they may seem like the same type of machine at first glance, there are, in fact, significant differences between an air cleaner vs air purifier.

Air cleaners are devices that remove dust and other allergens from the air to help relieve homeowners with allergies or asthma. You’ll find two types of air cleaners on the market, mechanical and electrical. Mechanical air cleaners have fans to carry the air through the unit, while electronic units use UV light to eliminate bacteria and airborne viruses.

Air purifiers are electronic devices that sanitize and circulate new, fresh air into any room in your home. They are designed to improve air quality and can eliminate pollutants and toxins from their designated room. Using either mechanical filtration, absorption, or a combination of the two, purifiers can remove harmful pollutants and strong odours, whereas air cleaners are primarily used to remove dust and allergens.

Air purifier vs. humidifier

Both an air purifier and humidifier can offer benefits for homeowners looking to improve the air quality in their home, however, there are key differences between the two devices.

An air purifier is an electronic device designed to remove harmful pollutants from the air and produce clean, fresh air into its designated room. Using a fan and filtration system, pollutants are trapped or eliminated and clean air is then emitted.

Humidifiers are not designed to clean the air, but rather add water particles to the air. These devices boil water and emit the resulting steam using an internal fan. Humidifiers are often used by households in the winter since they can help add needed moisture into any room in the home.

Can you clean an air purifier?

In some cases, such as if your device has a HEPA filter, those are better replaced than cleaned. However, there are plenty of devices on the market with reusable filters.

The best washable filter air purifiers for large rooms are designed to allow users to clean their filters with ease, so they can be reinstalled in the device and will continue to trap dust and allergens. To ensure you’re successfully cleaning your air purifier, wear protective gloves and a face mask so you don’t inhale any pollutants.

Next, unplug the device and clean the exterior with a damp cloth. On a low setting, vacuum the air intake grill and then remove the interior filters. Since an air purifier’s filters are delicate, be sure to gently clean them using mild soap and let them completely air dry to prevent mold. Once the filter is dry and ready to get back to work, simply reinstall it in the device and begin the clean air process again.

What is the best air purifier for large rooms?

The best air purifier for a large room is one that, ultimately, meets the needs of the buyer. There are several factors to consider before making your purchase. The size of the unit is important since the square footage will help determine which product can accurately purify the air in the room.

You want to ensure you’re investing in a device that has a proven record of helping customers find relief from harmful pollutants, which is why combing reviews and our helpful buying guide can help you determine which products are meeting consumer needs. For added protection, consider our air quality monitor reviews.

Lastly, consider which devices offer the best energy conservation. Energy Star-rated products have been certified by the EPA and promise the highest results.

Should you try an air purifier for large rooms?

If you’re looking for a safe and convenient way to improve the air quality in your home, our experts recommend investing in a standing or portable air purifier for large rooms. These devices are designed to remove harmful pollutants and replace them with clean air to keep those in the room safe and healthy.
