For many years people would add central vacuum systems to their new home construction process as this was both less expensive and more efficient than trying to add it after the home was constructed. While there are fewer central vaccum systems being installed today ( use of robots and less carpeting ) the advantage of a using a central system is still very effective.

Today, it is possible to add a central, whole-house HEPA air filtration system to your home both during and after construction. Pure Air Systems has been selling their 600HS PLUS, fan powered, commercial grade HEPA filtration system for homes, offices, hospitals, commercial buildings and industrial applications since 1985. This uint can be attached to any ducted, forced air HVAC unit with some minor ducting modificatioins and simple wiring. 

The system is designed to run anytime the HVAC unit runs and is really well suited to working with the newer variable speed drive HVAC units. The 600HS comes with a prefilter, carbon media filter and a true, certified HEPA filter. The advantages in having this type of medical grade air filtratoin system are many and, in this day of Covid-19, this type of system can be extremely beneficial in reducing the levels of airborne viruses in your home along with other allergens and contaminants.

While more Americans have decided to quit the smoking habit, almost 20% of the US population still smokes. Smoking is very addictive and difficult to give up. Many smokers try to limit their smoking to only the outdoors but this doesn’t work for everyone.

Many homeowners who smoke try to limit their smoking to one room to minimize the second hand smoke issues for the family members who are not smokers. While this seems like a good idea, the fact is that cigarette and cigar smoke easily travel along air currents and the odor can be recognized 50 feet away in another room.

Since most homes use forced air, ducted, heating/cooling systems, whenever the furnace or AC fan is on all the air from every room is pulled into the returns sent to the air handler, conditioned and then sent back out to the entire house through the supply ducts.  So, any smoke generated in any room in the house ( including the basement) will eventually be circulated throughout the entire home.

Pure Air Systems has dealt with this second hand smoke issue for many years, and very successfully. There are a number of methods using PAS filtration systems that can work for you.

First, you can place one of our model 600HS PLUS HEPA filtration units with carbon and variable speed motor with digital speed controller in the selected smoking room.  This unit can move up 600 CFM of air so if you sit next to the unit or place a small duct and hood on the inlet of the unit and smoke next to the system, the 600HS PLUS will pull out over 90% first pass of all the smoke (through the HEPA) and odor (through the carbon) and significantly minimize the amount of second hand smoke.

Second, you can use one of the new HPS series Portable HEPA units that again have both a HEPA and Carbon filter. This portable unit is considerably smaller than the 600HS PLUS unit (only 13″ sq. by 21″ long) and can move up to 500 CFM. It has a four speed air volume controller. Since this unit has a smaller intake area you will need to blow the smoke toward the inlet to allow for maximum capture.  First pass smoke and odor removal efficiency is slightly less than the 600HS PLUS but if used correctly the HPS unit can be the answer.

Third, you have the option of placing the 600HS PLUS or one of the larger HS PLUS units directly on the return air side of your heating/cooling system. The unit will remove the smoke and odor that is pulled through the return air grills in your home. However, this approach works best if you smoke near one of the main return air grills and you also have to make sure the heating/cooling fan is running at maximum speed to adequately pull the smoke to the unit.

Fourth, Pure Air Systems also offers a line of BioGuard media air filters that combine a polyester ring panel media with carbon. These filters replace the standard air filter located in your HVAC system and can be helpful in removing much of the smoke and odor from the cigarettes. Again, these filters work best when the heating/cooling fan is running and the smoke is generated near or close to a main return in the home.

Anyone of these options available through Pure Air Systems can be helpful in keeping second hand smoke from your family members. For more information on these filter products and smoking applications go to our website at: www.pureairsystems.com
