    Air Filter

    One of the most important steps of cleaning your air conditioning unit involves the replacement or cleaning of the air filters. These filters are usually referred to as HVAC air filters; an abbreviation for Heating, Cooling Air Conditioning Filters.

    AC filter


    Air Filters have a significant role in the air conditioning system. They are responsible for filtering dust and particulate matter to ensure better air quality of your indoor spaces. These particulate materials are trapped in the filters and do not get recirculated throughout your interior space.

    Types of Air Filters

    The proper type of air filters installed in your air conditioning unit is crucial for top-notch and long lasting system efficiency.

    Air filters of various types and with different purposes are available on the market , which is why it is important to determine the right types of filters and when to replace or clean them.

    1. Fiber-Glass Filter

    Fiberglass air filters are cheap and disposable options. They do a good job preventing large particles from infiltrating the space and they can also ease the burden on HVAC systems when drawing air inside.

    They are less effective, however, at blocking dust and other smaller contaminant particles. They are typically assigned a MERV 4 rating.

    2. HEPA Filter

    High-efficiency particulate air (HEPA) filters are recommended if you or any family members suffer from allergies or other respiratory issues.

    These are the most effective types for removing up to 99.97% of dust, pollen, mold, viruses, bacteria, and other irritants from the air, and they are more expensive than fiberglass or pleated air filters. Search for filters with a MERV 11 or higher for optimal performance.

    3. UV Filter

    Air cleaners that could be integrated into your HVAC system use UV filters. These filters eliminate bacteria, viruses, and other airborne microbes using UV light.

    They are an excellent choice if you have specific concerns or issues regarding indoor air quality with relation to microbial particulates. However, they are not very effective at removing dust and other contaminants from the air.

    4. Pleated Air Filter

    Pleated air filters are constructed from folds of cotton or polyester. Although they cost slightly higher than fiberglass ones, they are more effective at removing dust and other tiny particles like pollen and spores from the air.

    More pleated filters lead to better air filtration and reduce the chance of recirculating dust and other pollutants in the air. These filters usually have MERV ratings between 5 and 8.

    Cleaning Air Filters

    Cleaning air filters of your air conditioning unit is crucial to maintain a refreshing indoor ambiance throughout the summer.

    Air filters are core elements of your air conditioning system that ensure the quality of air flow across your interior spaces. With properly cleaned air filters, your system’s performance can quite significantly improve.

    ➜ Should I Clean or Replace Air Filters?

    The answer depends on the type of filters you are using for your air conditioning system. Different types of air filters have different functions and modes of operation. Depending upon the nature of air filters, you can choose either to clean them or to replace them.

    Many types of filters are reusable, meaning they can be cleaned and reused. However, other types of air filters are disposable ones. Such air filters should not be reused; but should be discarded and replaced with new ones.

    ➜ When Should I Clean Air Filters?

    The frequency of cleaning air filters of your air conditioning system depends upon its operational pattern. During summer, when the air conditioner use is at its peak, it is recommended to clean your air conditioner filters every 6th week for optimal performance.

    As for the rest of the year, when the air conditioner is not much in use, it is preferred to clean the air filters every 3 months. This also depends on how frequently you are using your air conditioner. At minimal usage in a clean environment, you can even reduce the cleaning frequency further.

    ➜ Condensation Drains

    Condensation drains are meant to drain humidity out of your room to reduce indoor humidity levels. However, condensation drains are susceptible to blockage which leads to pooling up of humidity in your indoor environment and reduced drainage.
