Quick Cool & Quick Warm When you need to cool down quickly or warm up faster, use the quick cool/warm mode to speed up the fan. Features three different fan speeds, for more cooling flexibility. Programmable 24-Hour On/Off Timer Customize times to fit your schedule for immediate comfort when you get home. The built in timer allows you to preset the unit to turn on and off in half hour increments. Our air conditioners maintain the preset room temperature, so you will remain comfortable at all times. Maximum comfort throughout the evening hours with the added benefit of energy savings. With Sleep Mode, the temperature gradually increases a few degrees over the evening. Allows you to precisely control the temperature and fan speed from across the room. With this feature, the electronic air purifier is energized to remove pollen and impurities from the air, improving your comfort. Our antibacterial filter reduces bacteria, room odors and other airborne particles for a healthier, more comfortable environment.

Comes with an extra long three-prong cord — makes extension cords unnecessary. Automatically resumes operating at its previous settings when power is restored to your unit. Alert notifies you when your filter needs to be cleaned so you don't have to keep track of it yourself. Easily select options with the touch of a button. Allow you to set the comfort level to your preference, while a convenient temperature readout displays the set temperature.No question is more likely to stir up a hornet’s nest of debate (if not brawl) among heating, cooling, and air conditioner (HVAC) professionals than “Which air filter should I use for my home?” Opinions vary so widely because over the years technicians have seen everything that the wrong kind of air filter can do to a home’s HVAC system: from coils, motors, and blowers too clogged by weak filters to burnt-out motors and controls because of too-restrictive filters. HVAC air filters are important for removing contaminants from the air to improve your home’s air quality.

The better the air quality, the better your HVAC system runs and the better your family’s health. Air filters are rated according to their Minimum Efficiency Reporting Value (MERV). guardian air purification system priceCreated by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), it’s a porousness scale that goes from 1 to 16, with most home air filters ranging from 4 to 13 MERV. allergy air purifiers san diegoThe higher the MERV, the more contaminants that are removed from the air.air purifier freshener Air filters are made from different materials in different thicknesses and sizes. These factors effect their MERV. Unfortunately, one of the biggest selling filter products, 3M’s Filtrete, do NOT use MERV, preferring its “Microparticle Performance Rating” (MPR) instead.

Fortunately, there is a place to compare the numbers. Be aware, too, that some retailers also use their own rating system instead of MERV. A decade ago, it used to be that if you had an HVAC system that used panel filters rated 6 through 9 MERV, putting in a MERV 11 or higher filter would restrict airflow (known as filter pressure drop). In turn, this would lengthen the system’s run-time, adding to your heating and cooling costs. This assumption is not entirely the case anymore. Newer pleated filtering media increases the filter’s surface area so that while the filter might be finer, there’s more area for air to pass through. The more pleats per foot, the better. The thicker the filter, the more surface area per pleat. So, while the filter pressure drop issue still has some impact, a 2009 Home Energy experimental test concluded that “…if no accommodations are made for the greater pressure drop of high-MERV filters, air flow and energy penalties are not likely to be severe — at least, not until the filter is loaded with dirt.”

If you are renting and do not have allergy problems or pets or live in an area with excessive dust, then buying cheap spun fiberglass filters with a cardboard frame every three months should work out fine. They’re not a good investment if you own your home because these filters are flimsy and prone to leak dust into the HVAC system. That dust can build up on coiling coils and motors and threaten to cost more over time in repairs than you might save from using cheaper filters. If you are going to invest in washable filters, then expect to pay more than $20 each for a 8 MERV filter. Cheaper washable ones will have loose filter media, especially after washing, and thus will perform poorly there after (caveat emptor). Keep in mind that disposable filters are more hygienic because all the dirt gets removed from your home when you toss out the filter. Higher MERV pleated filters do a much better job now that in the past. While the key to better filtration vs pressure drop lies in getting the most pleating per foot, it’s safe to say that newer filter designs have less air flow issues at higher MERV.

More important, they are more effective than the median-grade pleated filters at improving indoor air quality (and potentially better health) for you and your family. All the same, you still need to replace them every three months so price is a concern. For a standard sized 16″x25″x1″ 11 MERV filter, expect to pay $5 or more per filter but you can save a little when you buy them in packs of 12. Antimicrobial or electrostatic treatments also add to the filter’s cost. Some top brands within this general size range are Filtrete, Purolator, and Nordic Pure. Replacements for thicker (two to five inches) pleated 11+ MERV filters that require compatible framing to the air handler (see photo) and should follow the manufacturer’s recommendation because a thinner, cheaper filter won’t fit properly and so won’t work. While these filters are expensive – $45-$100 – they last a full year and work very well When it comes to air filters, all systems, homes, and air quality needs are going to be different.
