Those suffering from allergies and asthma stand to benefit most from purified air.

While the air blowing outside of the home is generally clear, the air inside the home often contains pollutants. Even mold spores can develop just from moisture in the air.

Forced-air cooling and heating can circulate bacteria and dust particles indoors. The presence of pets and smoking also spread toxins into the air.

Though many allergens are blown in through windows and doors, they also come from upholstery and carpet. You definitely need a Holmes HEPA purifier.

You may be thinking that your lungs are strong enough to weather such pollutants. Though it’s not too harmful to a those in good health with no underlying respiratory issues, it can harm children and those with allergies, asthma, or who are otherwise prone to respiratory inflammation. .

An air purifier is a great way to reduce air pollutants and help support healthy breathing. The pre-filter can capture dust as small as 0.3 microns—which is smaller than a grain of table salt. The carbon filter changes are economical and supported by attentive customer service.

How this air purifier uses HEPA technology?

HEPA (High-efficiency particulate air) is technology that uses filters  to meet energy standards for removing irritants and particles from the air. This filter can consist of any material as long as it meets the standard penetration of less than 0.3 microns and greater than 0.3 micrometers in size—meaning that the filter leaves just enough room for clean air to pass through, but not enough for common pollutants. The filter allows a specific adjustable amount of air to flow through the filter to ensure that air is being purified according to the size of the room it’s in and how many potential pollutants it needs to filter. The HEPA filters are capable enough to capture particles as small as 0.3 microns from air—smaller than a grain of salt. This purifier’s quality is backed with excellent ratings and reviews for its ability cleanse the air even in large rooms.

There are many air purifiers, but if you need to purify the air in a large room—say at least 10 square feet—use this purifier with a True HEPA filter purification process. Based on reviews, the clean air delivery rate of the Holmes Large Room 4-Speed HEPA Air Purifier can’t be beat; even the filter life is designed for durable, regular use. No matter what you choose, make sure to check the product specs, reviews, shipping terms, details, terms of use, filter replacement, model, privacy policy, packaging, feedback and product quality. Opt for products with 4- or 5-star reviews.

Things to consider before using an air purifier

You have to consider some things before buying an air purifier.

Buying the right air purifier

If you are searching for an air purifier, consider the technology and the current usage scenario before making a purchase. Consider the area to be covered, filter category, and, most importantly, clean air delivery rates.

Assess the area by measuring its coverage in cubic meters. Filters that use HEPA technology are considered the standard air cleaning and filter the smallest particles.

CADR is the unit used to measure  the hourly rate at which air in the home is purified; lower CADR means that your air is purified at a slower rate.

Placing the air purifier

Where do you place the purifier to maximize its use? This is an important factor to utilize its efficiency. The home air purifier should be placed in a way that easily maximizes clean air.

Placing the purifier too high or too low will reduce performance and operates best when it is not put in confined places.

Replace filter in a timely fashion

The purifier’s efficacy depends on its capacity for filters, so always check the HEPA filter and don’t forget to clean up for regular and longer life. Always consider good and well-known brands like Holmes so that it’s easier to purchase replacement filters. Check for the reviews before ordering online.

We all know purifiers are essential for the office and home because of increasing levels of in-house pollution. Those who want to safeguard their health should maintain their air purification. 

Close the door and windows

To maximize results, close the doors and windows while the purifier is on. Pollution indicators don’t reflect a change in ambient air quality. If you want your device to work efficiently, and think of it as being similar to an air conditioner, which needs a closed space to keep the cool air in.

Testing the purifier

Before buying an air purifier, test it in a closed place with polluted air. After the air purifier is turned on,  measure how much time it takes to remove the smoke and dust from the air. These procedures can be done to the entire filter, too, and used to check multiple units. Performance of air purifiers change from brand to brand; the buyer should look for air purifiers that have timers so that the unit can be set on or off when it’s not needed.

You can check if the filter has an indicator light so that you know when to change or clean the filter. Test the air purifiers using generators that release ozone into the air, which cause lung cancer in the future.
