Seasonal allergies are commonly triggered from ragweed allergies, fall allergies and spring allergies, the stuffiness and discomfort is annoying, many of us use medication usually, but a growing trend is to clean the air of allergens with an air purifier. This non-invasive approach is becoming more and more popular as medicines tend to lose their effectiveness over time and clean air can mitigate allergy symptoms.
Asthma rates in children are increasing, in fact, 1 in 11 now have some form of asthma. Part of this increase is due to a strong link between allergies and asthma, other asthma sources are related to smoke and air pollution. Steroids or other medications are commonly prescribed to help control asthma. But controlling asthma requires multiple methods and an air purifier for asthma can have great results.
All kinds of smoke are difficult airborne pollutants to remove since it contains hundreds of gases and particulates so it requires a high level air purifier. To effectively remove smoke add you'll need a high efficiency air filter, a strong motor, and carbon-based filters in your air purifier for your home.
No matter the season, pets like cats, dogs, and birds are either shedding their hair or losing old, dry skin throughout our homes. Then, our HVAC systems blow that pet dander throughout our homes and into our lungs. Your HVAC system control your air conditioning and heating, but air purifiers will clean your indoor air. Using a portable air purifier in common pet areas will capture the pet dander before it enters your immune system.
CADR stands for Clean Air Delivery Rate and it is the metric generated by old test methods dating back to the 1980s.
The CADR metric is a measurement of the clean air volume that a purifier can provide in a fixed amount of time and space – ultimately a measurement of the purification rate at maximum fan speed. It measures the amount of filtered air passed through a purifier.
The different test standards across the world for generating a CADR metric follow similar stipulations in how the test runs, and the chamber in which it should take place.
The test chamber normally is 30m3, depending on the methodology. It is a climate-controlled chamber, with solid walls, floor and ceiling. In the centre sits the purifier in question, and particle pollution is injected into the room from the outside through an aperture. A single sensor is installed in one side of the room to monitor the particle count in the room. There are also two fans – one wall-mounted and one ceiling fan – to aid air circulation.
Before the test begins, the purifier is placed in the centre of the room, manually switched on in maximum mode and ceiling and wall fans switched on. A controlled amount of pollutant is pumped into the room, the fans mixing and homogenising the pollutant concentration. At the start of the test, the ceiling fan is turned off, but the circulating fan remains running for the full test. It is conducted with dust, pollen and tobacco smoke, and runs for 20 minutes each time.
There are two measured factors that influence the CADR rating of the product tested:
a. the filter efficiency
b. the air flow through the filters.
The CADR score is calculated by measuring how much faster a purifier removes particles from the air compared to how quickly they would naturally drop and settle on surfaces. This is then multiplied by the volume of the test chamber – meaning that the chamber size is inextricably linked to the overall score.
