Air Purifiers and Filtration in Buffalo, NY

The EPA says research has not shown that UV light or plasma technology removes gases effectively in portable home units, and it warns against ozone generators, since ozone is a lung irritant. We avoid anything that produces ozone as a byproduct.

What do the EPA and local rules say about air cleaners?

The EPA says to avoid portable cleaners and furnace filters that intentionally produce ozone, and that no federal agency has approved ozone generators for occupied spaces. It adds that electrostatic precipitators, ionizers and some UV units can emit ozone, and that the California Air Resources Board and AHAM keep lists of devices tested to emit little or none. The EPA also notes that an ENERGY STAR label says nothing about how well a cleaner cleans air.

New York issues no statewide HVAC license, so Erie County Consumer Protection points you to your own municipality. Some towns license electricians, including Orchard Park. If a unit needs a new electrical connection, ask your town or village what it requires.

Spring brings tree pollen and cottonwood fluff, and late summer brings ragweed. Pets, cooking and a damp basement add their own load, and some summers bring wildfire smoke that travels in from far away. On those hazy days, keeping windows shut and running filtration is the usual approach.

Furnace-based filtration has a built-in limit. The EPA notes that a furnace or air handler filters air only while the system runs, usually less than a quarter of the time in heating and cooling seasons. Running the blower on a continuous low setting, where the equipment allows it, helps. A portable HEPA unit in the bedroom fills the gap on smoke days.

1. 1Learn what you want to catch. Pollen, pet dander, smoke, or just less dust. Each one favors a different answer.
2. 2Measure what the system can take. Return size, filter cabinet depth and blower type decide how dense a filter we can use.
3. 3Pick the lowest-cost fix that works. Sometimes that is a better filter and a sealed slot. Sometimes it is a media cabinet. We name the cheaper choice if it will do.
4. 4Install and test. We mount the unit, confirm that airflow holds up, and check the system runs as before.
5. 5Teach the upkeep. You learn what to change, how often, and what a clogged element looks like.

Not necessarily. We cannot promise relief from allergy symptoms, and no honest contractor can. The EPA treats filtration as a supplement to controlling the source and ventilating, so washing bedding, controlling humidity and keeping pets off beds count too.

HEPA filters are very effective, but they resist airflow too much for most home furnaces. That is why portable HEPA units are the usual answer for a bedroom, while the central system gets the densest filter it can handle. If a whole-home purifier does fit your system, we explain how it works and what it does not do.

Portable cleaners are sized by CADR, a particle-only rating. The EPA lists these minimums for an 8-foot ceiling, and taller rooms need more:

Boiler and radiator houses have no forced air to carry a central filter, so a portable cleaner is often the only filtration they get. The EPA adds that activated carbon is what removes gases, and the thicker the carbon bed, the better.

We do not publish prices, so we do not have a figure to quote here. The main factors are the type of equipment, whether a new filter cabinet or duct modification is needed, the electrical connection, and how easy the furnace area is to reach. The quote comes before any work starts.

• Whether a basic filter swap is enough, since that is the cheapest change and the first one to try.
• The depth of the cabinet and whether the return duct must be modified to fit it.
• How often the media has to be replaced. The EPA says standard furnace filters typically need changing every 60 to 90 days.
• Electricity, because the EPA notes that longer blower run times raise power use.

Replacement parts matter as much as the purchase price. A media filter has to be changed on the schedule its maker sets, and a purifier cell or lamp has its own. We tell you the upkeep cost up front. For the basics of filter swaps, see our guide on how often to change your HVAC filter.

• Set a reminder for filter changes, and write the install date on the cabinet.
• If the system sounds different or airflow drops, call us. The filter may be too dense.
• Keep the area around the furnace clear so air can move freely.
• Ask about duct repair if leaks are sending dust into the system.
