Top Ten Best Air Purifiers 2017- Making the air you breath cleaner and healthier

Whether you’re suffering from allergies or simply want to enjoy cleaner, fresher air in your home, air purifiers have come a long way. Some air purifiers are small desktop units that give you the ability to enjoy cleaner, filtered air while other air purifiers are full-size units able to clean larger rooms. Air purifiers are essential for anyone who wants to live and work in spaces free of dust, odors, mold, pollen, dander, tobacco smoke, and other irritants. Air purifiers are essential items for anyone suffering from allergies, asthma, or dealing with respiratory ailments.

 

Tips for Choosing an Air Purifiers

Before investing in a quality air purifier, it is essential that you make a thorough checklist of what you need the air purifier to do. Air purifiers come in a wide variety of models, capabilities, sizes, and styles, so it’s a really good idea to know ahead of time what you’re looking before before narrowing down which model is right for you.

Filter

The most important component of any air purifier is its filter. Some models of air purifiers have filters that must be replaced at certain intervals. Other models of air purifiers have filters that can be cleaned, adding longevity to the device at the price of requiring more maintenance.

Many air purifiers use a HEPA filter, an ultra-dense screen of overlapping fibers that capture small particles in the air. Other techniques for purifying air include ion generators that capture particles using electrostatic techniques and UV filtration that irradiate and render sterile bacteria.

Some air purifiers even use a combination of different filtration technologies to capture and/or render harmless air particles.

 

Noise

Although many of today’s most advanced air purifiers are rated as “whisper quiet”, there is no such thing as a completely silent air purifier. All air purifiers rely on a fan to move air through the filtration system, and this will generate some sound. More powerful air purifiers that clean larger volumes of air more rapidly will necessarily also create more noise, so always take into consideration where and how you plan on using your air purifier and what impact, if any, its operation will have on the people in the room.

 

Room Size

Whether you’re planning on using your air purifier in a single room or office or will be moving it around on a regular basis, it’s important to calculate the size of the room to be cleaned before investing in a quality air purifier. Manufacturers of air purifiers will generally list the maximum room size that their model can clean, but this specification refers to the upper range of what the device can clean. It’s generally a good idea to buy an air purifier rated for a room slightly bigger than the space where you plan on using it in order to ensure a steady supply of clean, fresh air.

 

Causes of Indoor Air Pollution

Although you may disagree with the word “pollution” for what is occurring inside your home or office, air purifier manufacturers design their devices according to what type of particulate matter it can best remove from a given volume of air. Airborne irritants in the home can vary, but are generally categorized as: odors, particles, and gases.

Odors refer to everything from food smells to tobacco smoke that you want to strip from the air. Poor ventilation can also cause a build-up of stale air, sometimes known as “stuffiness”, and a good air purifier will help keep the air smelling fresh by ensuring that your interior space gets enough ventilation.

Particles refer to small physical particulate matter that floats through the air, including dust, dander, pollen, and other natural substances that can aggravate allergies. Gases can include gas produced by an oven/stove, a fireplace, personal hygiene items (like hair sprays) as well as ordinary household items that release gas, including building materials, furniture, carpets, and painted surfaces.

As different models are more efficient at cleaning and filtering different types of irritants, it is essential that you first assess what kind of cleaning you want before deciding on the right model for you.

 

Important Considerations Before Buying an Air Purifier

Air purifiers come with a sometimes bewildering amount of technical terms and specifications. Here are a few things to look for when choosing your next air purifier:

CADR

Otherwise known as the Clean Air Delivery Rate (CADR), this refers to the ability for your air purifier to strip out pollutants like pollen, smoke, dander, and dust. Although not every manufacturer lists their air purifier’s CADR rating, it’s important to remember that a higher number is better.

 

Air Flow

This refers to the volume of air that can be cleaned by an air purifier, usually expressed in cubic feet per hour. This specification is sometimes known as the “air change per hour”, and depends on the type of filter and the speed of the fan. It’s important to remember that a faster (higher air flow) air purifier is not always necessarily a better one, only that it cleans larger volumes of air in a given amount of time.

Some manufacturers refer to this as the ACH or Air Change per Hour rate. An air purifier with a rating of 5 ACH means that the air in the room will be cleaned five times in an hour, or once every 12 minutes. Remember that these specifications always refer to the air purifier working at top speed, so the ACH will be less at lower fan speeds.

 

HEPA

First released on the market in the 1950s, HEPA or High Efficiency Particulate Air filters use a web of special fibers to strip out particulate matter, dust, dander, and even mold spores from the air. HEPA filters differ from non-HEPA filters in the way that the fibers of the filter are arranged. A non-HEPA fiber usually has an overlay of fibers that contains symmetrical gaps that allow air to pass through. A true HEPA filter is designed in such a way that the fibers are overlaid irregularly and thus trap, diffuse, and impact particles in the air. HEPA filters are able to trap or deflect particles 0.4 microns in size or larger.
