Buying Guide

Just as it’s unreasonable for a hunter to go hunting without a weapon, it is equally unreasonable for a buyer to go shopping without having adequate knowledge about what he wants to buy. We don’t want you to be this sort of buyer, so we urge you to read the buying guide below.

How can a purifier improve your life?

Increase your productivity

Improved air quality always brings about increased productivity. This is especially true if you work from home, like cleaning and purifying your air indoor can make a significant difference. When the level of the indoor air pollutants reaches a certain point, you can become lethargic and fatigued which will cause you to be feeling sleepy at all times. Also, low indoor air quality (IAQ) can cause symptoms such as headaches that will significantly slow you down. Install a whole house air purifier to improve your productivity instantly.

Help you sleep better

A poor IAQ usually makes it hard to sleep peacefully and comfortably. Air pollutants are capable of increasing cases of sleep disorders such as snoring and reduce your sleep’s efficiency. In the long run, inadequate sleep or lack of can raise your risk of severe conditions like cardiovascular diseases. In case you are not getting adequate sleep, an air purifier can get rid of the pollutants that are possibly causing that.

Ease asthma and allergy symptoms

If you are asthma or allergy sufferer, any sort of indoor air pollution can trigger you. Dander, pollen, and dust circulating through the atmosphere may result in a stuffy nose, itchy eyes and other unpleasant symptoms you wouldn’t like. A product like the Aprilaire 2410 can eliminate up to 99.97 percent of airborne pollutants, and the three-stage filtration system incorporated in the device can get rid of particles as little as 0.3 microns.

Features to consider while choosing a whole house air purifier

Below are some key factors you need to consider before buying your whole house air purifier.

Happy-Indoors
Coverage area

Usually, whole house air purifiers are capable of covering larger areas as compared to room models, with some models even having the capacity to cover several thousands of square feet.

As a general guideline, you need to go for a model whose coverage is a bit larger than your home’s real size to make sure you are making the most out of it. If you’re looking for a model with very wide coverage, we recommend you to choose the AIRMEGA 400.

Type of filters

This is perhaps the most crucial thing that you need to consider when looking for the right whole house air purifier. It is imperative to comprehend that the air isn’t cleaned automatically. It is actually run through a particular filter which then captures the unsafe particles, before introducing the air back into the building. While there are different types of filters, you might want to choose a HEPA true model, which guarantees to remove at least 99.97% of airborne pollutants.
However, despite being the most efficient and safest filtration method for airborne particles like dust, mold, dust mites, and pollen, HEPA filters are less effective for things like gas molecules, odors, Formaldehyde and OCs. Therefore, activated charcoal air filters are used in situations that require the removal of airborne chemicals, gaseous pollutants, fumes, and odors. Most manufacturers use the combination of both, plus UV filters and ionizers for maximum effect.

Maximum noise level

Noise level is crucial, particularly if you use a purifier in a room where you work or sleep. For maximum quietness and efficiency, we recommend choosing a bigger unit and operating it on a lower speed, instead of turning up a small model. Consider an ultra-quiet model like the Alexapure Breeze Air Purifier if you’re looking for quietness.

Warranty

Most air purifiers come with a warranty of two years at least. Some companies try selling you additional extended warranty while some try to take your contact details for this. Make sure you check and read the terms of the warranty and what it covers.

Also, check if the warranty will be voided by customer action. For example, most warranties will only apply to the original buyer and won’t transfer to succeeding owners.

Extra features

Also, check if the unit comes with additional features such as the intelligent air quality sensor which automatically detects the air quality and adjusts accordingly. Also, check if it has multiple speed settings and an auto shut-off feature. However, keep in mind that fancy features usually increase the cost considerably. For instance, look at the Alen BreatheSmart which is equipped with all the fancy features but will cost you quite a lot.

FAQ

If your house is approximately 1000 square feet, that would be like a mountain too big to climb for a portable air purifier since they usually are not designed to cover wider However, there are portable models on our list that are capable of covering 800, 1000 and even 1600 square feet. So if you’re looking for a compact, budget-friendly purifier, take a look at Alen Customizable Air Purifier.

Of course, yes. Depending on the model and brand, a whole house purifier can help get rid of pet odor and cigarette smoke in your house. Look for the purifiers that are equipped with a true HEPA filter and activated carbon filters for optimum results.

Our Verdict

Our runner-up choice is the Alen BreatheSmart Air Purifier, which is also the most customizable option on our list. Not only does it come with a wide range of features, but it is also backed by a lifetime warranty.
