Whole House Air Filter System: The Ultimate Guide

Are you looking for a way to improve the air quality in your home? A whole house air filter system may be the answer. In this guide, we'll explain how these systems work, what types of filters are available, and how to choose the right one for your home. In a whole-house system, dust and pollen particles are charged as they pass through the unit, and then captured on an oppositely charged collector plate. Portable ion filters, which operate without fans, send negative ion currents directly into the air.

Our air purifiers help create healthy air for the whole house, not just the space or room, and can help reduce triggers for allergy and asthmatics. With our Pure Fit promise and event-based cleaning with programmable thermostat, delivering healthy air to your home has never been easier. In Auto (similar to medium; the Air does not contain a particle counter to adjust to air conditions, but instead asks you to enter the approximate size of your room, after which the machine chooses a fan speed that Molekule deems appropriate), the air performed worse, reducing particles from 0.3 microns in only 18.0% (ambient) and 26.4% (clean). In Silent, it performed even worse, reducing 0.3 micron particles by 6.5% (ambient) and 7.2% (clean).

And in Dark plus Auto, with its primary PECO purification system turned off and its fan at the equivalent of a medium setting, it reduced them by 21.3% (ambient) and 18.0% (clean). Interestingly, those numbers closely reflect our results in automatic configuration with the PECO system activated, suggesting the possibility that the Molekule Air relies primarily on its physical prefilter, not its patented PECO mechanism, to remove particles. Extended media filters are one type of whole house air filter system. Imagine a stack of oven filters about 8 inches thick and you have the idea of an extended media filter. In addition, Cabiclean and Durabasics filters fit perfectly into the machine, hermetically sealing their edges to prevent unfiltered air from escaping another important factor in HEPA performance.

Whole house filters, such as the extended media filter shown here, must be professionally installed in return air ducts. Throughout its promotional literature, Molekule used to claim that its PECO technology “completely destroys particles in the air” and contrasts it with HEPA purifiers, which, according to the company, cannot capture viruses or anything smaller than 0.3 microns (in fact, they can and do), release mold and bacteria return to the air (they don't) and cannot capture VOC (true for HEPA filters, although their secondary VOC filters can).These systems are passive; while the fan is running, they constantly filter all the air in your home. Because activated carbon filters don't fight particles, many air purifiers have an activated carbon filter and a mechanical filter to trap particles. On the other hand, in HEPA purifiers, a fan draws airborne particles through a dense felt-like filter that has billions of small voids of different sizes. Some media outlets have incorrectly stated that HEPA filters do not filter below 0.3 microns and therefore cannot capture airborne coronaviruses. Models listed are compatible with Clean Air MERV 11, Healthy Home MERV 13, Odor Reduction MERV 13CBN and Allergy & Asthma MERV 16 filter types. The best way to improve indoor air quality is to eliminate pollutant sources and ventilate with fresh, clean outdoor air. In fact, those filters are designed to protect your oven from large dust particles, and while they can keep surfaces in your home a little cleaner, they won't block microscopic particles that are more irritating to lung tissue. If the air quality is poor and you don't have an air purifier, an HVAC filter attached to a box fan is better than nothing. The Winix 5500-2 is a direct competitor to the Coway AP-1512HH Mighty, having a nearly identical clean air delivery rate (CADR) and offering 5.1 air changes per hour (ACH) in a 350 square foot space.
