Guides on Choosing A Best Air Purifier 2017
Why We Need An Air Purifier?
An air purifier is a device that cleans the air in a room from contaminants and pollutants. In this post, we will talk about air purifier reviews and how to choose one. Air purifiers can remove up to 99.97 percent of pollutants as small as 0.3 microns. They’re even more effective at removing larger-sized pollutants. Dust, pollen, tobacco smoke, mold spores, pet dander, bacteria, viruses and others are all eliminated. By removing the pollutants and allergens, the purifiers will protect you from breathing diseases and contagious diseases like allergies, asthma and flu.
Investing in a high-quality best air purifier can help you sleep better, have fewer allergic reactions and overall improve your health.
Reasons to buy an air purifier
If you or one of your family members frequently have allergic reactions, sneeze all the time or have a respiratory condition such as asthma, an top air purifier can help reduce the probability of attacks. When you are having an allergic reaction, your body reacts to otherwise harmless elements such as pollen and dust mites as if they were dangerous viruses. This is the reason why during an allergic reaction you may have a runny nose, itching skin and eyes, and nausea. When you do have allergies, it doesn’t really matter to you that pollen or other substances causing the allergies are not otherwise harmful. What matters is that they are the reason why your body is having an allergic reaction. A quality air purifier removes pollen, dust and other particles from the air and helps solve the issue.
Air purifiers also help prevent other health conditions from developing. The issue here is that just like with cigarettes: the government is slow to recognize the long-term effects of air pollution. For example, there are over 80,000 chemicals in use in the United States. Out of this number, only about 25% have been tested in regards to their effect on human health. Because of this, it is better to be safe than sorry and an top rated air purifier can help you accomplish just that.
If you have pets, your home inevitably has pet dander, fur, and hair. The walls in your home don’t just protect you from the outside world. They also keep pollutants such as gases, odors, and particles inside of your home. In April of 2016, CNBC reported about a study by the journal called Science of the Total Environment. In the study, researchersclaimed that indoor air can be more dangerous than the polluted air outdoors. (Source: http://www.cnbc.com/2016/04/22/indoor-air-can-be-deadlier-than-outdoor-air-research-shows.html) An best rated air purifier will make the air inside of your home cleaner and healthier.
Living next to a garden or a forest
Gardens, forests, trees and even lawns can create mold spores. The spores can then easily get into the air and get inside of your home, triggering allergic reactions. Protecting yourself and keeping the air in your home clean is especially important if you have a weak immune system or have chemical sensitivities.
Your home smells dirty, stuffy or stale
Sometimes bad smells may be coming from your neighbors. Cooking odors are a very common problem in apartment buildings and condo complexes. It is also possible that you live not too far from a busy roadway or an industrial area. Both heavy car traffic and industrial activities can release dangerous particles into the air.
There can also be a lot of simpler reasons, from playing sports to smoking, as to why your home just doesn’t smell right. If that’s the case, an air purifier may be just what you need to keep the air inside of your home clean, fresh and pleasant to breathe. In this post, you will also air purifier reviews of some top best ones.
Moving to a brand new home
Moving to a brand new home can be very exciting. However, the air in a new home can be filled with pollutants and chemicals that remain in the home long after the construction is over. One of the most common pollutants in new homes is formaldehyde, which is known to lead to health problems. An air purifier can help you make sure that the air in your home stays clean. This is especially important if you live with young children or senior citizens.
Types of Air Purifiers – How Air Purifiers Work?
Below you will find a description of most popular types of technology air purifiers use to clean the air. Depending on the type, an air purifier can remove the following from the air: dust, mold spores, smoke particles, dirt particles, pollen, pet dander and various organic compounds.Each type has its own pros and cons, which is why an air purifier may have more than one filter and use more than one technology.
Filter air purifiers, including purifiers with HEPA Filters
A filter air purifier works by moving air through a filter and capturing particles smaller than a certain size. This is what makes it different from other types of air purifiers, some of which remove negative ions or gas particles from the air.
Air purifiers with HEPA filters are some of the most popular top rated air purifiers on the market.
The letters HEPA stand for High-Efficiency Particulate Air. The first HEPA filter was designed during the World War II. It was used to clean the air from radioactive particles. Commercial manufacturers have been using the technology since the 1950s. HEPA air purifiers are very popular on today’s market.
HEPA is a type of an air filter that needs to adhere to an official government standard. You can find HEPA filters not only in air purifiers but also in vacuum cleaners, passenger cars and airplanes and certain medical devices. According to the United States Department of Energy, a HEPA filter needs to remove from the air at least 99.97% of particles that are 0.3 microns in diameter.
This is about one-third from the smallest particle that a human eye can see, which is why HEPA filters catch elements including mold, bacteria, and chemicals that are not visible to the human eye. Another benefit of HEPA filters is that they do not generate any harmful byproducts, including ozone gas. So, if you want a high quality products, we recommend hepa air purifiers.
A HEPA filter also needs to have a certain resistance to airflow.
Attention: HEPA-like is not the same as HEPA
In todays’ air purifier reviews, we need to stress one thing. A manufacturer can’t claim that a device has a HEPA filter if the filter does not correspond to the government standards. For this reason, there are a lot of products on the market with labels “HEPA-type,” “HEPA-style” and so on. Unless the label says “HEPA” on it, the filter is not a High-Efficiency Particulate Air filter. Most respectable manufacturers do not use such gimmicks.
The more often you use your air purifier, the cleaner the air will be. However, your filter will also become full quicker. Typically, a HEPA filter in an air purifier lasts somewhere between two and four years.
One of the disadvantages of HEPA filters is that they do not remove odors or gases. For this reason, many manufacturers create air purifiers that use a combination of a HEPA filter and some other particle trapping mechanism, such as activated carbon.
Air Purifiers with UV Technology
Air purifiers with UV technology have a UV lamp installed inside. As the air passes through the purifier, the UV lamp kills bacteria and viruses. One of the issues with UV technology is that it doesn’t do anything to airborne pollutants such as tobacco smoke, which is why air purifiers that use UV technology typically have a filter. The most effective best air purifiers first run the air through a HEPA filter or an activated carbon filter. They then use UV rays at the last step in the filtration process.
UV rays can turn oxygen and water into ozone gas, which can be a harmful pollutant. A good UV air purifier minimizes the creation of ozone and other harmful substances.
Air purifiers with activated carbon filters
Activated carbon or charcoal filters have an extremely large absorption area, which makes them great for capturing chemicals and gases such as tobacco smoke, emissions, and odors. For example, a gram of activated carbon filter has a surface area that exceeds 30,000 square feet. Such filters have a lot of small pores that do an excellent job of trapping gas molecules.
Air purifiers with negative ion technology
Air purifiers with negative ion technology use electricity to charge the molecules of air. Negative ions are particles with one or several added electrons. Such particles attract airborne particles including pollen and dust by using an effect that works like static electricity. At a certain point, the newly formed particles become too heavy to stay in the air and fall onto windows, walls or floors. While this technology does sound advanced, it has proven to clean the air less effectively compared to other types of air purification methods.
The issue is that this method doesn’t remove the particles from the air. It simply moves them from one place to another in a room. When new molecules stick to floors and other surfaces, they still have the ability to enter the air again. For this reason, an air purifier with negative ion technology may not be the best choice you can make.
Ozone air purifiers
Ozone air purifiers intentionally produce ozone gas, which can be harmful to your health. Exposure to ozone can cause an asthma attack or scar the lungs. As a result, many government agencies do not recommend using ozone-generating machines. For example, Air Resources Board of California Environmental Protection Agency states that ozone can cause respiratory tract irritations. Because of this, the Board recommends not using ozone generators at home at all.
We also have a very long article about how air purifiers work.
How to choose an air purifier
Start with your needs
In the previous section of this guide, we have discussed different types of air purifiers and their advantages and disadvantages. When choosing an air purifier, start with your needs.
If you have asthma or allergies, choose a device that with a HEPA filter. Such a device will remove most dangerous particles from the air.
If you have health issues that appear when there are odors present in the air, choose an air purifier that has odor and chemical filtration.
If you live with a smoker and need to clean the air from tobacco smoke, you can choose an air purifier that has been specifically designed for this goal.
You can also find devices on the market that have been created for people with multiple chemical sensitivities or MCS.
Choose the right size of an air purifier for your room
Calculate the area of the room where you will be using your new air purifier. You can do that by measuring the width and the length of the room in feet and then multiplying these numbers. The result will be the square footage of the room. Next, look at air purifiers that have your square footage in their specifications.
Decide where you will put your air purifier
Air purifiers can be large, which is why you want to make sure that you have enough space for the device.
Portable air purifiers usually do a good job purifying the air in just one room. If you want clean air in multiple rooms, you may need to invest in several devices. Typically, you would want an air purifier in your bedroom because your bed is where you spend 6-8 hours a day sleeping. If you are shopping for an air purifier for your bedroom, make sure that you are getting a device with a noise level that you can tolerate. When buying an air purifier for high-traffic areas, get a device with variable settings that can clean more air faster if you need it to do so.
Don’t forget about maintenance
Air purifiers aren’t cheap to own or maintain. A replacement HEPA filter for your device can cost as much as $100. Electricity to operate an air purifier can also cost you up to $100 a year or so. To find the exact numbers and costs, read the manual and the maintenance requirements for the model you are considering before you invest in a device. Make sure that they are acceptable to you. Investing in an air purifier that has a timer is one of the ways to cut maintenance costs.
What You Need to Know: Air purifier functionality
Air exchange rate
I believe you have heard of this term. Air exchange rate shows you how much air an air purifier can clean in a unit of time. The higher the number, the faster the device can work. For example ACH (air charge per hour) of two means that the device will filter the entire volume of air in a room twice in an hour. If you have asthma or allergies, look for a device that can filter the air at least 4 times in an hour. Instead of ACH, some manufacturers use CFM. CFM stands for cubic feet per minute. You can calculate how quickly the purifier will clean the air in a room by calculating the volume of your room in cubic feet and then dividing this number by the CFM rate of your air purifier.
Filter change indicator
If you do not want to track when you need to change filters in your air purifier, choose a device with a filter change indicator. Such devices typically have counters that will alert you when it’s time to change the filter. Some air purifiers get the information about filter change by actually measuring the state of the filter.
Not all air purifiers have fans. Some clean the air that flows through them naturally, but they are not very effective.
If an air purifier has multiple fan speeds, you will be able to variate the speed with which the purifier cleans and recirculates the air. Typically, the higher the fan speed, the more noise the purifier makes. Test the device or watch some videos of it in use to make sure that the levels of noise are acceptable for your goals.
The issue of noise is especially important if you plan on placing an air purifier in an area where you work or sleep. Overall, it is better to invest in a bigger, more expensive air purifier, and run it at a slower speed, than buy a small device that you will need to run at a high speed all the time.
Some air purifiers come with a remote control that allows you to control the settings of a device. Typically, these settings include speed, power, timer, Ionizer settings and UV settings.
When an air purifier has a timer, you’ll be able to turn it on a few hours before you start using a room. You can also set it to turn off automatically during certain periods of the day. This functionality can save you a lot of money in the long run because it can significantly improve maintenance costs.
Air Quality Sensor
Some air purifiers come with built-in air quality sensors. The sensors adjust the performance of the purifiers based on the quality of the air. Certain models of air purifiers even have sensors with LED light systems that visually indicate the levels of air pollution in real-time. If you choose an air purifier that doesn’t have an air quality sensor, you can always buy an air quality sensor separately. The best sensors available on the market today measure temperature, humidity, levels of dust, ozone, carbon dioxide, carbon monoxide and air pressure. They connect to your smartphone and show both current measurements and historical data.
In order to keep maintenance costs low, some manufacturers create air purifiers with washable pre-filters. The job of such pre-filters is to catch the largest particles. The air then goes through other filters. Because there’s a pre-filter, more expensive and thorough filters don’t get dirty as quickly. This makes them last longer and saves money on maintenance. However, many of the high-performing air purifiers do not come with this option.
If you have a small room, then a small air purifier may do just fine. If, however, you need to purify the air in a large room, look for a model with appropriate capacity.
