CADR Explained CADR, the Clean Air Delivery Rate is a metric that was developed as a way of measuring the performance of residential air purifiers. The CADR reflects the volume of air in CFM (cubic feet per minute) that is cleaned of particles of certain sizes. To measure the effectiveness in removing different particle sizes, three types of particles are tested: smoke, pollen and dust. These represent small, medium and large sized particles. Each is measured and assigned it’s own CADR score. The advantage of the CADR is that it gives the consumer a way to compare
Health. It’s really the most important aspect of our lives. Without your health it’s hard to to anything. Growing research has shown that adding an air purifier can make a huge difference to your health and quality of life. Whether it’s preventing heart disease or helping students at school, air purifiers play an important role. So, we introduce 10 reasons everyone needs an air purifier. 10 Reasons Everyone Needs an Air Purifier 1. Allergies – Seasonal allergies are commonly triggered from ragweed allergies, fall allergies and spring allergies. Yes, the stuffiness and discomfort is annoying. Many of us use medication.
HEPA filters were first developed during World War II by the US government as a way to create an effective gas mask. Little has changed with HEPA filter media since then and it remains the most effective way to remove particulates from the air. What is a HEPA filter? By definition, a HEPA filter removes 99.97% or more of particles that are sized 0.3 microns and larger. Allow me a moment to get nerdy and explain why the standard is based on 0.3 microns. The reason for measuring the HEPA filter efficiency at 0.3
Air purifiers can play an important part of an overall strategy to breathe cleaner air. Whether that be for asthma or allergy relief as well as gas, smoke and odor removal. The question though is, do air purifiers really work? To assess whether an air purifier will work for you it is important to know what you are looking to remove from the air, how sensitive you are to the pollutant, and the size of the space that needs cleaning. In our Education Center we provide buying guides to help you through this process.
The most common place an air purifier is used is in the bedroom. This is because it is the place where we spend most of our time at home. So this begs the question. What’s the most effective bedroom air purifier? In our experience the air purifiers that work best for people suffering from allergies, asthma or other respiratory issues are those that filter at a high efficiency, move a sufficient volume of air and are relatively quiet. While that may sound simple, it is quite difficult to perform well in all areas since they
We’ve written previously about the impact pollution and air quality can have on health. Now we turn to air pollution and heart health. This year, China has been undergoing what’s been dubbed the “airpocalypse” as pollution levels reach deadly highs. Many parts of the United States also have similar crises on a smaller scale, not just in big cities. Areas with lots of factories or vehicles can have higher concentrations of ozone, which lead to increased asthma attacks, hospital admissions, and even death, especially in older adults and during the warmer seasons. Pollution and ozone
While we talk a lot about indoor air quality, the health benefits that come from breathing clean air inside can be undone by breathing low quality air outdoors. Asthma, Ozone, AQI Explained The biggest contributor to air quality is ozone. Ground-level ozone that we breathe mostly comes from reactions of man-made VOCs (volatile organic compounds), most commonly from chemical plants, gas pumps, and print shops. When you inhale ozone, it reacts with molecules in your lungs and can cause coughing, irritation, chest tightness, shortness of breath, and even pain and burning sensations. Breathing in air
