Things to Consider Before Buying Air Purifier for Your Home


Our health is significantly impacted by air quality. Air pollution exposure can cause major health problems like allergies, asthma, and other respiratory disorders. By removing pollen, mold spores, pet dander, and other airborne contaminants, air purifiers are regarded as an amazing approach to cleaning the air. The air purifier collects and holds viruses because some viruses need to be connected to an object in the environment, such as a water droplet or dust particle, lowering the danger of transmission in the process.

Finding the right air purifier for you might be difficult because there are so many different models available in the market. Air purifiers are created with specific uses in mind. For allergic eczema, they contain numerous filters to eliminate allergens, and for asthma, they have filters to do the same. Some air purifiers feature dedicated filters for hazardous gasses, pet dander, and smoke.

Previously a luxury, air purifiers are now a requirement. However, there are many choices available on the market, making it challenging to make a decision. This blog is for you if you intend to purchase an air purifier. Here is a list of things to think about before purchasing an air purifier.

Things to Consider Before Buying Air Purifier for Your Home

  1. Determining The Size Of Purifiers

It is very important to analyze the size of air purifiers to buy the correct one for your room. Small air purifiers will obviously not function in vast settings. You can select the best model if you know the exact dimensions of your space.

Evaluate the square footage of the room you wish to filter when selecting the appropriate size air purifier for your requirements. The finest air purifiers for people with allergies and asthma are those that can clean the air in a room at least four times each hour.

Compact: These air purifiers are for small spaces, such as 299-square-foot rooms.

Medium: Locate an air purifier for spaces 300–699 square feet in medium size.

Large: Place these air purifiers in 700–1,900 square foot spaces.

  1. Area And Air Purification Rate

The efficiency of any air purifier is gauged by its CADR, or clean air delivery rate. The air purifier cleans the air at this rate. The performance improves as the CADR value increases. POLAR is another such indicator that assesses how well air purifiers are functioning in a residential environment. The number of times clean air is replaced with stale air inside a room every hour is known as the air change rate or ACH. The ideal ACH rating is between 5 and 6.

The amount of air that needs to be cleaned and how quickly it needs to be cleared determine how effective an air purifier is. Essentially, the two basic components are referred to as CADR and Coverage Area. An air purifier with a lower CADR can effectively clean a smaller space, but a bigger area cannot. However, an air purifier that covers a bigger room and has a higher CADR would use more electricity. These factors will give you an idea of the after-maintenance cost and productivity of your air purifier.

  1. Smart Features Consideration

You must consider some smart features in an air purifier. They can help you buy the right one that could not only be efficient but also ensure the longevity of the product. Below are the features you must consider in the air purifier you are planning to buy:

  • Caster wheels, grips for simple mobility, remote controls, different fan speeds, and filter replacement indications are additional features that you can think of.
  • Wi-Fi air purifiers that you can operate with your phone are also available.
  • To save money and protect the environment, search for EPA-certified Energy Star air purifiers.
  • Real-time information on your air quality is provided through sensors of air quality.
  • After determining the quality of the air in the space, an air purifier with an air quality sensor mechanically modifies the fan speed. The unit is also turned on and off as necessary.

  1. Considering the Maintenance Costs

The major type of upkeep required for air purifiers is replacing air filters. Here are some rough estimates that could give an idea of the cost of maintenance, which is another important factor to consider before you buy one.

  • Pre-filters typically last three months, however, some can be cleansed for prolonged filtration.
  • HEPA filters have a lifespan of around a year, depending on consumption.
  • Other kinds of air purifiers sterilize your air by using heat or UV light to destroy allergies and pathogens. For your comfort, these models never require filter change.
  • Filters made of activated carbon typically last six months.
  1. Guarantees And Customer Support

A consumer should take into account the product’s after-sales services while choosing an air purifier. Because filters need to be cleaned and replaced every 12 to 18 months for air purifiers, it is particularly crucial. Filters can occasionally cost as much as the air purifier that needs to be maintained. Trouble-free filter replacement is possible with excellent customer service and sufficient warranties.

  1. Consider Noise Level And Energy Usage

An air purifier’s operation will be more unpleasant the louder it is, and you might only be able to use it during the day. As a result, make that the device you choose does not generate noise that is louder than 40 to 50 db. The device will then be able to be used at night. Air purifiers consume far less energy than other appliances you could use at home, such as a computer or air conditioner.

You can also take into account extra elements like maintenance expenses, warranties, the reputation of the manufacturer, and servicing accessibility prior to purchasing an air purifier. Maintain balance when evaluating features and costs. Examine many models that give the characteristics you want, and then choose the one that best matches your budget.

Before purchasing an air purifier, it is crucial to comprehend how it keeps you healthy. As an outcome, you will be able to determine whether you actually need an air purifier. These are a few ideas to help you select the best air purifiers for your particular needs.
