When choosing an air filter for your Ballard home, there are many options. Each type of material is designed to capture a different type of particle to a different degree, so make sure you choose carefully based on the specific air quality problems your home has.
- Disposable – Disposable filters are the simplest and least expensive option on the market but they are usually rated as low as 1-5 MERV and don’t last very long. These types of filters are usually designed for basic mechanical filtration to stop debris from causing problems for your furnace or air conditioner and are therefore not ideal for actual air quality improvement.
- Fiberglass – Fiberglass filters are very common in almost all HVAC systems and are more permanent than disposable filters. They come in MERV ratings of between 4 and 12 and are highly efficient at capturing larger particles like dust, pollen and dander. These can be dangerous, however, as they fragment and can send fibers into the air.
- Polyester – These have a higher resistance rating than most fiberglass filters and are therefore more durable against larger particles like dust and pollen. They also don’t fray like fiberglass and are more durable over time.
- Electrostatic – Electrostatic filters have a charge to help collect dust particles and are usually made with multiple layers of polypropylene material.
- HEPA Filters – This is a completely different category of filters and is designed to capture everything as small as 0.3 microns – well below the threshold most commonly provided by standard HVAC filters. They can be purchased for your HVAC system or as standalone filters for individual rooms.
There are a number of different filter types to maintain the air quality in your home. If you’re interested in getting the most out of your home’s air quality control system, make sure you do it with the best possible device available to your system.
