However, I have read many air purifier reviews where air purifiers did not help with allergies. However, I find that it is important to find the model and brand that can alleviate your specific allergy. I learned this after spending few months of my salary trying out various air purifier models. I created this review site to help others in choosing an air purifier that works, without wasting months of salary. Let me know if it does help you.
How To Choose The Right Air Purifier? The ideal air purifiers are the models that remove the most pollutant particle from your house. When you are doing your air purifier review, there are many factors you need to consider carefully. The list of factors that can affect the effectiveness of an air purifier includes your house size, whether you have pets, and even where you stay. It is important to choose the best air purifier for your needs, based on multiple factors that matter to you. Below we list a number of factors that we deem important in evaluating an air purifier. CADR number is provided for tobacco smoke, pollen, and dust.
AHAM recommends that the room size is at most 1. 5 times the CADR value for tobacco smoke. However, depending on your needs, you might need to get several air purifiers even for a medium-large room. There were times that I put two air purifiers in my bedroom when I felt really bad. By the way, CADR is tested with the highest fan speed. You might want to keep this in mind when making your decision. Most if not all of the air purifiers for home are safe to use.
However, some models produce ozone or other gas chemicals that are known irritants of our respiratory system and can aggravate asthma. The design of an air purifier determine its air purifying performace. Here it’s important to match the product that you are considering with your actual needs. For example, carbon filter is required to filter odors from the air. The air purifiers in the market range from basic models, with only fan speed knob, to advanced models with all the bells and whistles one could imagine. But remember not to get yourself overly carried away with all these features during your air purifier review because in the end, the most important is still how good the air purifying performance is.
Some of the air purifier features are self explanatory, but many of the advanced features need more detailed descriptions. Here I describe some of the features that I hope will make it easier for you to decide on a specific model. HEPA air purifiers are very common in the market. They work well, reliable and proven to be effective and safe. HEPA filters need to replaced regularly. The frequency to replace the HEPA filters depend on the product. HEPA filters in air purifiers that are equipped with pre-filter need to be replaced less often.
In the market, you will see the term True HEPA, which companies use to show that their air purifiers are certified to meet HEPA standard. To my knowledge, True HEPA filters are not washable, so you will need to replace them regularly as they trap all the air pollutants. These lower grade filters could be enough for your needs, so don’t rule them out yet. Remember how static electricity can pull your hairs standing? Ionizer works with similar principal. Ionizer doesn’t need filter replacement. However, it needs regular cleaning as the plates will be covered with all the dusts and dirts.
So it’s very unlikely to cause problem or irritation to the respiratory system. By the way, ionizer air purifier is completely different with ozone air purifier. Ozone air purifier works by producing significant amount of ozone. For asthma patients, the ozone produced can potentially aggravate their conditions. HEPA filter is generally not enough to remove odors, so if odor removal is important for you, be sure to buy air purifier models that come with carbon filter. Pre-filters are used to prolong the lifetime of the subsequent filters. True HEPA filters are expensive to replace, thus by using the pre-filters, the lifetime of the HEPA filters can be extended and pre-filters will save you money in the long run. Pre-filters could be replaceable or washable. I like washable pre-filters as they save me money on replacement of the pre-filters. But the replaceable pre-filters are generally more efficient than the washable type.
