How to Buy Air Purifier Filters

When you own one or more air purifiers, filter changes are just a fact of life. If you're getting ready for your first filter change, you may have some questions about how to order new filters for your machine. Here are the three key steps you'll need to take when it's time to buy new air purifier filters.  

  1. Know the Make and Model of Your Purifier

  It's very important to realize that filters are not interchangeable between models. To get the right filter, you'll need to know the make and model you're using. This information, along with filter part numbers, can be found in your owner's manual. If you no longer have the manual, the model name of the purifier will usually be displayed somewhere on its housing.  

  2. Select Your Filters

  In some cases, there may be more than one filter option for your purifier. If you're using a Blueair purifier, for example, you may have the option of adding a SmokeStop filter to your device for better odor and gas control. Be sure to look at all available filter options and choose the one that is best for your particular needs.  

  3. Order Only From an Authorized Dealer

  Once you know what filters you need, it's time to buy. Before you do, though, it's absolutely critical that you find an authorized dealer for your purifier's brand. Buying from unauthorized dealers online can lead to serious problems, including getting knock-off filters that won't be nearly as effective as those made by reputable manufacturers. By ordering from an authorized dealer, you'll protect yourself against frauds and make sure you get the product you need.   By following these three simple steps, you can find out which filters you need, select from the available options and order the genuine article with relative ease. Once you've gone through the process once or twice, you'll find that it's no problem for you to get the filters you need.   Have questions about air purifier filters? We're here to help!

Should I Leave My Air Purifier on When I'm Not Home?

Once you buy an air purifier, you'll find yourself asking all sorts of questions about optimal maintenance and use. One of the most common questions we get is whether you should leave your air purifier on while you aren't at home. Here's what you need to know about leaving your air purifier on while you're out of the house and why we recommend running it 24/7 instead.  

The Pros

  Leaving your unit on will help to ensure that particulates and gases are being removed from your home air, even if you aren't there. It will also make sure that your home air is as clean as possible when you return from work, preventing you from having to wait while your air purifier cycles the air through.  

  The Cons

  The only downside of leaving your air purifier on while you're away from home is that it can use up a bit of extra electricity. However, as we addressed in our article on air purifier energy costs, the actual expense of running an air purifier isn't that high. So, while you could save a bit of money by turning your unit off when you're leaving for work in the morning, it certainly won't be much.  

  Our Verdict

  Ultimately, we think it's better to leave your air purifier running at all times to maintain the highest possible home air quality. While you'll spend a little extra money on electricity, the results are definitely worth the investment. Leaving your purifier on at all times also saves you the trouble of having to remember to turn it back on every time you come home.   Have other questions about how to use air purifiers or which model is best for you?

3 Signs It's Time to Replace Your Old Air Purifier

On this blog, we've written many articles for first-time air purifier users. However, it's also worth noting that even the best air purifiers wear out over time, and many people are using models that are badly outdated. Here are three of the top signs that it's time for you to buy a new air purifier.  

  Your Air Purifier Eats Up a Lot of Electricity

  If the unit you're using is adding a substantial amount to your electrical bill, it's a good sign that it's time for a replacement. Older air purifiers were major energy consuming appliances. Today, however, the machines have become more efficient and less expensive to operate. For the best energy efficient upgrades, check out our complete lineup of Energy Star certified air purifiers.  

  You Start Hearing Unusual Humming or Buzzing

  If your air purifier begins making unusual and loud noises, it generally means there's a problem. While newer models will likely still be under warranty, a unit that has been in your home for 10 years will have long since passed its warranty expiration. In this situation, it's generally better to replace your air purifier, as repairs are costly and difficult to arrange.  

  The Purifier Isn't Cleaning the Air Properly Anymore

  Of course, the biggest sign that it's time to get a new air purifier is that your old unit simply isn't doing a good enough job of cleaning the air anymore. While you should make sure that the problem is with the machine itself and not with the filter, air purifiers are not immune to wearing out. You can check how well your unit is cleaning the air by measuring your indoor air quality with a Foobot meter, which will allow you to get quantifiable data on the contaminants in your home air.   If you're in the market for a new air purifier, consider one of our excellent residential units. If you aren't sure what you need, feel free to send us your questions, and we'll be happy to provide answers and personalized product recommendations based on your needs.

3 Hidden Air Quality Dangers in Your Home

While there are some common chemicals that everyone knows are bad for human health, it is often surprising just how many harmful substances can be found in the average home. If you go looking, you'll be amazed to discover what you might be exposed to on a daily basis. Here are three of the most common air quality dangers that are present in almost every modern household.  

  Formaldehyde

  Used to treat construction and insulation materials, formaldehyde is also a dangerous chemical gas that can cause upper respiratory irritation and exacerbate chronic respiratory conditions. Even though formaldehyde is usually only present in low levels in most homes, it may be enough to affect those with severe sensitivities to chemicals and gases.  

  Mold

  Even if your home is pristine and clean, you may still have hidden patches of mold lurking in places you'd never imagine. Mold can grow in any damp, dark environment, making it difficult to avoid. Meanwhile, mold releases spores that can trigger allergic reactions, and some types even produce harmful gases and odors.    

  Dry Air

  Even if there aren't any contaminants in your air, you could still be suffering from the effects of low humidity. Dry air can cause irritation of the mouth, throat and respiratory system, as well as headaches and dry skin. Even the cleanest air can be too dry and cause problems for people breathing it.  

  How to Check Your Indoor Air Quality

  If you aren't sure what the status of your indoor air quality is, consider using a Foobot air quality meter. This meter measures particles, VOCs, temperature, humidity and other air quality characteristics to paint a complete picture of how healthy the air in your home is.   Have questions about air quality or how to use a person indoor air quality meter to improve the air you're breathing?

Childhood Asthma Linked To Household Mold

While it has always been known that exposure to mold is far from healthy, new research continues to demonstrate just how hazardous mold in homes with young children can be. One of the most concerning findings of recent years is the link between mold exposure in infancy and the development of asthma in later childhood. Infants who are exposed to high levels of mold by the age of 8 months are more likely to develop asthma by the time they are 7 than other children. Although the mechanism by which mold contributes to asthma development remains unknown, the evidence for such a connection is quite strong.  Even without this risk, having certain varieties of mold in your house could be dangerous. Mycotoxins produced by mold have been linked to everything from acute toxic poisoning to higher long-term risks of certain cancers. As a result, it's important for all homes, especially those with young children, to take steps to prevent mold growth.. What Makes a Home Turn Toxic? Not all mold is hazardous to one’s health, nor do all homes wind up playing host to mycotic cultures. But once mold starts growing in your home, it can quickly affect your health. Anywhere there is humidity and insufficient ventilation, mold spores can take over. Since mold can grow on any organic material provided sufficient moisture, even materials in  areas which are not readily visible, like roof materials above ceiling tiles and flooring below carpet. The insulation in air ducts can also be mildewed and rotting, resulting in increased respiratory and other health complaints. Combating Mold in Your Home by Minimizing Excessive Moisture The key to avoiding mold in your home (or place of work) is keeping humidity low. Making sure there is sufficient ventilation in all rooms can be a tricky task; even seemingly harmless houseplants can encourage the growth of mold. But before you throw out your favorite decorative plants, be aware that there are a number of ways to combat excessive moisture indoors. If certain areas lack sufficient windows, you may want to  supplement the airflow with a dehumidifier or fan to minimize excessive humidity in your home. For rooms that will  inevitably get damp, like bathrooms, it is advisable to avoid carpeting, which will be hard to dry out and so encourage the growth of mold. If mold is found in the home, it should be cleaned up with bleach as quickly as possible. Insofar as the presence of mold in a home has been positively  linked with the development of childhood asthma, it is vital that mold not be allowed to grow unchecked in homes, schools, and workplaces. Although it is not necessarily proven that mold causes asthma and other health conditions, the strong correlation between the presence of mold spores and prevalence of respiratory distress, certainly implies that mold, at the very least, exacerbates symptoms. While there is nothing we can do to avoid our genetic fate, investing in fans or dehumidifiers and cleaning air ducts now may prevent serious health problems down the line. For mold protection, we recommend coverage from a high-quality HEPA air purifier such as the IQAir HealthPro, Amaircare 3000 or Austin Air HealthMate. Purifiers that feature a VOC canister can also help to control odors, making your home more livable while you are tackling an existing mold problem.
