Sometimes yes, sometimes no. It depends if there is space between ceiling joists. You need at least 24 inches opening between joists for the air cleaner. If you have adequate clearance, an attic crawlspace installation is similar to the drop ceiling scenario. Cut the appropriate sized hole in the ceiling material and finish the edges with the supplied trim. You'll need to use mounting hardware to support the weight of the unit from a suitable part of your building's framework.

No. Both smoke air cleaners are made to fit in the space of either one or two standard ceiling panels. The air cleaner's light weight outer casing is installed first. Then you can slide in the collection cell and pre filter. Not at all. Wiring is about as complicated as ceiling fan. A do-it-yourself attitude and set of homeowner's tools is all you need to wire an SE 400 or SE 800 commercial air cleaner; however, if special building codes apply, it is recommended that you adhere to them.

The SE400 and SE800 are designed to run 24/7, but in most cases, they will not need to run constantly. A good practice is to turn the air cleaner(s) on high speed prior to opening time, to get a head start on air circulation ? this helps reduce the chance of your air cleaning equipment having to play "catch-up." Once patrons start rolling in, you may choose to reduce the air cleaner fan speed if high speed is not necessary.

Snowblowers do not have air filters. Normal operating conditions are essentially dust free. Your air intake is ducted such that it is shielded from flying debris and the muffler serves to preheat intake air. Air filters would also be prone to icing.

Yes, although care must be taken to ensure the Desert Spring Humidifier is not subjected to freezing as this will damage the unit and may cause leaks. Units located above a ceiling should also include the installation of the overflow line. You can reduce the risk of freezing by carefully insulating the incoming water line, 6 inch flex duct, and humidifier unit itself with fiberglass insulation (be sure not to put insulation directly against the motor).

The HealthMate unit or the AllergyMachine will clean an average bedroom in about 15 minutes with the door closed. In technical terms, they clean up to 1,500 square feet. The HealthMate Jr model cleans up to 700 square feet. (All estimates assume 8 ft. ceilings.)

Once squirrels get cozy in your attic or walls, they can make a mess and cause a lot of damage that can cost thousands of dollars to fix. They will also return year after year, using your attic as a home base — they have no problem living alongside humans. The hole squirrels use as entry will become a great place for leaks to form and a passageway for other animals, including other rodents, bats, honeybees and insects.

No. In most homes, the Dynamic will install in an existing 1" filter slot. In a few cases, a filter track may need to be installed. Dynamics require a 24 volt power input. This can be taken either off the 24 volt system of your furnace or from a plug-in transformer supplied by EDG.

However, the question should be: "Does my crawl space have higher mold levels than what is found in the outside air?" When checking for mold, 10 minute air samples need to be compared to the same outside, which is considered to be the baseline. A visual inspection is also possible, but not as conclusive.

Answer: Generally we say 18 inches, however that distance is just a recommendation. The actual height should be enough to allow for routine maintenance of support systems. The appraiser must have access to the crawl space, and enter to the extent of head and shoulders at a minimum. The appraiser must look for evidence of infestation, rot or any other detrimental conditions. Answer: The subject property should not be rejected.

Only if you have un-sealed gaps between your attic and your living space. Such gaps are often found in closets, around light fixtures, and around utilities such as electrical outlets, pipes, etc.

Seal up the largest air leaks in your house--the ones that whistle on windy days, or feel drafty. The worst culprits are usually not windows and doors, but utility cut-throughs for pipes ("plumping penetrations"), gaps around chimneys and recessed lights in insulated ceilings, and unfinished spaces behind cupboards and closets. Better yet, hire an energy auditor with a blower door to point out where the worst cracks are.

The Space-Guard High Efficiency Air Cleaner utilizes a simple and effective HEPA-type filtering media that actually improves its particulate-capturing capability the longer it is used. The filter unit is attached to your heating or cooling system. There it seizes pollutants from conditioned air before being distributed to rooms in your home. Depending on your type of furnace, there are two models of filters available. The model 2200 is adaptable to upflow or horizontal duct configurations.

A device containing a filtering mechanism (filter), which is designed and used for collecting airborne impurities, such as, dusts, gases, smokes and fumes through the use of filters, electrostatic cells and/or absorbents. Typically an air cleaner has a motor blower.

Generally speaking, for an adequate air exchange rate, you can expect up to 500 sq. ft. coverage for the SE400E, and around 700 sq. ft. for the SE800E. - based on moderate concentration levels w/ 8 ft. ceilings. Individual results will vary based on environmental variables. To find out how many of which air cleaner you need, try our air cleaner calculator in the Buyer's Guide.

Consider that if a sewer backs up in a dirt or gravel crawl space it is impossible to effectively clean it. Even removal of the gravel or dirt will still leave residual contaminants. Sealing the crawl space with a vapor barrier and laying a 4" concrete slab floor will result in no more sewage!

We consider an ABC concrete floor system a mini basement. Use your crawl spaces for storage as you would a basement.

We recommend three weeks, as there will be some residual water content emitted as the concrete cures.

Even a gravel crawl space will increase the humidity of the air. Remember that a crawl space is just a hole in the ground and water will be attracted to that area. Gravel works well as a cover-up and to hide this condition. Gravel will also add a tremendous amount of dust in your house, especially if you have a forced air heating system.
