When it comes to air quality, the effectiveness of air filters is measured using a scale called the MERV rating table, which stands for Minimum Efficiency Reporting Value. The cheapest disposable air filters are between one and four on this scale, while microparticle air filters are known to be rated higher than 14%. Unfortunately, washable filters usually rank very low on the scale, with a MERV rating of between 1 and 4, meaning they aren't very effective at capturing the microscopic particles that tend to lower your home's indoor air quality. Washable or reusable filters can be rinsed with water or vacuumed to remove any build-up of particles.
They are usually made of woven polypropylene and are electrostatically charged to capture more particles. While they can be reused, making them more environmentally friendly than disposable fiberglass filters, they are also more expensive. Pleated filters are the most common type of oven filter. They can be highly efficient and durable, usually having a MERV rating of 5 to 12 and a very long lifespan. Pleated filters have an extended surface for better airflow. An electrostatic air filter is designed to trap smaller particles more efficiently than standard air filters.
Electrostatic filters are available as disposable and washable options. However, they also have a higher price. Disposable filters are more effective at trapping smaller particles, while washable ones are only good for protecting from large particles such as dust. They don't filter pet dander, bacteria, viruses, or smoke, especially when they're not changed often enough. Disposable air filters are less expensive, but it is recommended to replace them at least twice a year.
There are a lot of variables at play when considering cost, so be sure to consider these factors when choosing the best HVAC filter for your home. As air enters the vents and return ducts, it flows through the air filter to remove dust, debris, and any other particulate matter suspended in the air before the air conditioning system conditions the air. Particles that remain lodged in the filter can slow down the HVAC system's essential air flow over time, which can lead to costly problems. Disposable filters don't need any routine care because you can throw them away and put them in a clean filter when they get dirty. Most washable filters last at least ten years, so you should be fine if you plan accordingly and carefully care for your washable filter when you wash it.
Pros and Cons of Washable Electrostatic Filters
If air purity and filtration are important to you, especially if you have a health problem that requires it, then you can opt for a disposable filter. Replace it in your air conditioning system (following directional airflow guidelines, if any) and the ventilation airflow will completely dry out the clean air filter. On the other hand, if you have furry pets, the electrostatic filter may not remove as much pet dander as you would like.Let's face it, it's annoying to have to go to the hardware store every month or two and search through a variety of air filters until you find the right size. The air filter is designed to protect both the mechanical components of your furnace and your home's indoor air quality from airborne particles. As these particles suspended in the air pass through the medium, they become positively charged and quickly adhere to the next layers of the electrostatic filter, just like static accumulates on the feet of a sock when walking on a carpet or iron filings are attached to a magnet.
Conclusion
When deciding between disposable and washable electrostatic filters for your home's HVAC system, consider factors such as cost-effectiveness, environmental friendliness, convenience of use and maintenance requirements. Disposable filters may be more cost-effective in terms of replacement costs but may not provide as much filtration as washable electrostatic filters.On the other hand, washable electrostatic filters may require more maintenance but can provide better filtration over time. Ultimately, it is up to you to decide which type of filter is best suited for your home's needs. Consider all factors before making your decision so that you can ensure that your home has clean and healthy indoor air quality.
