Whole-Home Air Cleaners and Filtration Equipment

AIR FILTRATION CLEANERS

The most effective way to enhance the quality of air in your home. State-of-the-art Carrier air filtration systems such as the InfinityÂ® Air Purifier and Performance Electronic Air Cleaner effectively remove bacteria, pollen, animal dander and other pollutants as small as 0.01 micronsâ€“that’s 18,000 times smaller than the head of a pin. The higher the MERV rating, the more efficiently the cleaner removes particles.

Shemtov Systems – To the Rescue of Your Indoor Air Quality

Are you concerned about the quality of air in your home? All the homes are equipped with HVAC systems as maintaining the temperature of the home is relatively important. Having good ventilation reduces the energy bills by keeping the energy flow inside the house and reducing the exchange of air from outside which is filled with dust and pollutants. Also, install an air cleaner system if any family member is allergic to dust and pollen. Air cleaner systems get rid of airborne allergens and pollutants and even smoke to help you and your family to breath clean air easily.

Shemtov Systems is a trustworthy service company with an experience over 30 years in handling HVAC systems. Air conditioning, heating, furnace, air cleaners and all other possible units’ installations and service are done by them at an affordable cost. Any trouble at home will be resolved within a day of reporting and they even come to your rescue by offering after hour services for those in need of emergency service. The main priority of the team of Shemtov systems to make you live comfortably in your home without HVAC systems troubling you.

Shemtov systems are experts in air cleaner services and you will be surprised at how much the quality of air changes after they finish their job. The function of the air cleaner is to remove the microscopic pollutants and molds present in the air by filtering them. So the air filters in them are prone to clogging if they are not regularly maintained. A certified technician or a professional does the job of cleaning the filters or replacing them to make them give their peak performance for years to come.

The technicians are certified to do air cleaner installations, air cleaner repairs, and air cleaner replacements after they have done the air cleaner diagnostic test on your system. They even give suggestions on how to reduce the energy bills and replace the parts which are old and faulty. Having outdated systems is one of the main reasons for the rise in energy bills. Shemtov systems are fully equipped with a variety of new systems which can be installed at your home as per your need. In case of system replacement, the company will give you a free estimate of the cost and offer you the best deal on the new system.

Whole-home air cleaning splits into two families: deep pleated media held in a cabinet at the air handler, and electronic air cleaners that charge particles and collect them on washable plates. What separates them in practice is the particle size you need to catch and how much static pressure the duct system can give up. Call Shemtov Systems at 240-355-3333 to compare filtration for a house in Silver Spring or the wider county.

Key takeaways

MERV runs from 1 to 16, with separate capture requirements in three particle size ranges.
A MERV 8 filter has no requirement below 1 micron; that is the gap between it and MERV 13.
EPA points homeowners toward MERV 13, or as high as the fan and the filter slot will allow.
AprilAire numbers its filters so the last two digits give the MERV: 210 is MERV 11, 213 is MERV 13, 216 is MERV 16.
Cabinet depth rather than the MERV number decides how much airflow a filtration upgrade costs.

What do MERV numbers actually measure?

The ASHRAE test scores a filter in three bands, 0.3 to 1.0, 1.0 to 3.0, and 3.0 to 10.0 microns, with a minimum in each. MERV 8 must remove at least 70 percent from the coarse band, which holds most pollen and visible dust, and 20 percent from the middle band. MERV 11 adds a 20 percent floor in the finest band and raises the other two to 65 and 85 percent. MERV 13 requires 50, 85, and 90. MERV 16 requires 95 across all three.

Media filter or electronic air cleaner?

Deep pleated media is passive: nothing to power, nothing to wash, media swapped on a schedule. An electronic air cleaner charges particles in a first stage and collects them on plates you wash rather than discard, and its efficiency falls as those plates load. Devices that ionize or generate ozone raise a separate question: EPA notes that the FDA holds indoor medical devices to 0.05 parts per million of ozone, and that some ozone generators sold as air cleaners exceed health guidelines even when run as directed.

How does filtration affect airflow?

Most residential air handlers are rated to move their airflow against roughly half an inch of water column of external static pressure, and everything in the air path spends part of it: ducts, coil, registers, filter. A clean 1 inch filter at MERV 13 can take a fifth to a third of the budget by itself, and its share grows as it loads. The same media grade in a deeper cabinet has several times the surface area, so resistance drops. Measure first: see duct pressure testing.

Whole-home or portable: what does each do well?

A whole-home cleaner treats everything crossing the blower, which also means it only works while the fan is running; a variable-speed blower left on continuous low keeps it working between heating and cooling calls. Portable units are rated by clean air delivery rate for smoke, dust, and pollen, and clean one room regardless of what the ducts are doing. Pairing them is common: filtration at the air handler, a portable unit in a bedroom.

What do Montgomery County homes need to filter for?

The tree canopy drives a long spring: oak, maple, and pine pollen, then grass into early summer, then ragweed and mold spores through humid late summer. Those are mostly coarse particles a MERV 8 to 11 filter handles. Wildfire smoke and combustion particles from cooking and traffic sit below 1 micron, which is the case for MERV 13 wherever the ducts can carry it. A house with a crawl space or pets carries a heavier settled dust load year round.

Frequently asked questions

Is a higher MERV always better?

Only if the system can move air through it. A filter the blower cannot pull against cuts airflow across the coil, cuts capacity, and can ice an evaporator in summer. Match the step to cabinet depth and measured static pressure.

Do air cleaners remove odors and gases?

Particle filters do not. Odor control needs activated carbon, which AprilAire sells as a carbon blend version of its filters, model 213CBN in place of the plain 213. Gases such as VOCs respond better to source removal and ventilation.

How often does whole-home filter media get changed?

Deep media commonly runs 6 to 12 months depending on pets, dust load, and blower hours. A 1 inch filter in the same house needs changing several times a year, which belongs in any cost comparison.

Is an air cleaner the same thing as an air purifier?

In everyday use an air cleaner filters particles, while air purifier often describes equipment adding ultraviolet light or another active technology alongside a filter. Worth pinning down which a quote means, since the two are not rated on one scale.
