Choosing the Right Air Purifier for Your Home

We often prioritise physical health through exercise and nutrition in today’s fast-paced world. However, we might overlook one critical aspect that affects our daily well-being – the air we breathe. Air purifiers have become vital for indoor spaces as the levels of pollutants and allergens in the air continue to rise. The challenging living conditions in metropolitan areas, where pollution levels have skyrocketed, have made it difficult to find fresh, clean air. Fortunately, air purifiers offer a reliable solution to combat these issues.

Indoor air pollution is a silent concern, and selecting the right air purifier can significantly impact air quality within our homes. Buying an extended warranty is better for increasing your air purifier’s lifespan. If you have further queries regarding the extended warranty and AMC for all air purifier brands such as Kent, Daikin, BlueStar, Samsung, Carrier, etc., download the OneDios app today. 

Here are some essential steps to help you choose the perfect air purifier for your home, ensuring fresh air for you and your loved ones.

1. Identify Your Needs

Determine why you need an air purifier. Do you or your family members suffer from allergies, asthma, or other respiratory conditions? Are you concerned about pet dander, smoke, or odours? Do you live in an area with more dust or construction work? Identifying your specific needs will help you narrow your options and find an air purifier that addresses your concerns. OneDios app makes it simple for the consumer to avail of the post-sales services without difficulties. 

  • Medical conditions like Asthma and Bronchitis- HEPA filter with Activated Carbon
  • Allergic Rhinitis – Allergies due to pollen, dust or pets – HEPA filter, UV light
  • Safeguarding Immunity – HEPA Filter, Cold Catalyst Filter, Activated Carbon, UV Light
  • Safety from smoke – HEPA Filter with Activated Carbon/Ionic filter/ Charcoal filter
  • Pollution and unpleasant odours – HEPA Filter with Activated Carbon/Ozone filter/ Charcoal filter

2. Understand Filtration Technologies

Air purifiers use different filtration technologies to trap and eliminate pollutants. The most common type is the High-Efficiency Particulate Air (HEPA) filter, which captures particles as small as 0.3 microns. Activated carbon filters are effective against odours and volatile organic compounds (VOCs), while UV-C technology can kill bacteria and viruses. Research each technology to determine which one suits your requirements.

  • Pre-Filter – To prevent the HEPA filter from becoming clogged, it is recommended to use a pre-filter. This filter captures larger airborne particles such as dust, pet fur, and non-woven fibres.
  • Antibacterial/ Germicidal filters aid in killing bacteria, germs and dangerous microorganisms.
  • High-Efficiency Particulate Air (HEPA) Filters can effectively eliminate 99.5% of airborne smoke, mould, and dust particles, even those as small as 0.3 microns that are invisible to the naked eye. This makes them an excellent choice for individuals who suffer from allergies.
  • Activated Carbon/Charcoal/Ozone filter uses porous carbon to trap impurities like unpleasant odours, smoke, and chemicals. However, it is not effective at removing allergens or chemicals entirely. 
  • Photocatalytic Oxidation (PCO)/ Cold Catalyst filter oxidises and breaks down harmful pollutants like formaldehyde, benzene, ammonia, and TVOC.
  • Ultraviolet filters use UV light to neutralise harmful germs and microorganisms, providing clean and safe air. However, it may not suit those with allergies or sensitivity to chemical fumes, smoke, or odours.
  • The ionisers / Ionisation filter releases electrically charged ions into your home, which bond with potentially harmful pollutants using a mild electrical field. As a result, these pollutants can no longer float around and instead either fall to the ground, where they can be vacuumed up or are attracted to filter plates. This is a highly effective way of filtering out tiny airborne particles such as smoke and dust.

3. Consider Room Size

The size of the room plays a crucial role in selecting the right air purifier. Air purifiers are designed to clean the air within a specific square footage. Measure the room’s dimensions and choose a purifier that can effectively clean the air within that space. Oversized purifiers may consume excess energy, while undersized ones will be less effective. If you plan to buy an air purifier, you should also purchase an extended warranty. Why not raise a service request on OneDios?

4. Check the Clean Air Delivery Rate (CADR)

CADR measures the efficiency of an air purifier in removing specific pollutants. It’s essential to match the CADR values with your room size and the types of pollutants you want to target. Look for air purifiers with higher CADR ratings in categories that matter most to you, such as pollen, dust, or smoke.

5. Noise Levels

Some air purifiers can generate noise, which might be disruptive in specific environments. Consider models with lower noise levels if you plan to place the purifier in your bedroom, office, or any other quiet area. Check product specifications and user reviews to understand how noisy the purifier is during operation.

6. Filter Replacement and Maintenance

Air purifiers require regular maintenance to function effectively. Filters need replacement after a certain period to ensure optimal performance. Before purchasing, check the filter replacement schedule and costs. Air purifier filters must be replaced and appropriately cleaned; otherwise, they will harm your health. Some models offer washable filters, while others require replacements. Factor in maintenance costs when making your decision. To replace the filters of your air purifier, contact OneDios.

7. Energy Efficiency

Energy consumption concerns many users since air purifiers run continuously to maintain air quality. Look for models with an Energy Star certification, as these are designed to be energy-efficient without compromising performance. This choice can lead to long-term energy savings and a more environmentally friendly option.

8. Budget-Friendly Options

Air purifiers come in various prices, from budget-friendly to premium models. Set a budget that aligns with your requirements and explore options within that range. Remember that the initial cost isn’t the only factor; consider long-term expenses like filter replacements and energy consumption. An air purifier AMC plan or extended warranty would help you care for all your air purifier maintenance and repair needs. At OneDios, you can also schedule the air purifier service in advance.

9. Customer Service and Warranty

Always go for a brand that has excellent customer service. After-sales and installation service should always be top-notch. As it establishes the company’s brand and fosters confidence. Read customer reviews because they can help in brand differentiation. AMCs make the task of maintaining air purifiers relatively easy and convenient. 

It is crucial to select air purifiers from brands that offer a warranty allowing you to repair or replace the purifier or its parts in case of any fault or breakdown. More extended periods of warranty showcase the brand’s trust in its product. Choose an air purifier with the most extended warranty.
