How To Choose the Best Furnace Filter for Your HVAC System

by Barbara 4. November 2015 04:56

Question: How do I choose a furnace filter for my HVAC system?

Answer: Always check with your HVAC technician prior to replacing your furnace filter. He or she is knowledgable about the air duct capacity and motor capacity of your system. Another option is to match the furnace filter in your system with another that is the same MERV rating or  MPR (Microparticle Performance Rating)‎. Explain that the 1 inch filter has an internal frame, that no air can go around it. Similarly the 4 inch thick unit is made to fit a 4 or 5 inch filter slot.

The buyer of a furnace filter must assume responsibility for his or her choice of furnace filters. No on-line company nor box store knows the age, the air duct capacity, the motor capacity, etc. of your HVAC system. Only your HVAC technician is qualified to determine the density of a filter that will work in your furnace and cause no problems.

Safe Home internal frame filters have two layers of media. The white side must be inserted into the filter panel so that the air flow goes through that part first. With the internal metal frame, this filter fits very tightly into the opening. No air can go around it. Your HVAC technician needs to know that this is an internal frame filter with no air escaping around it.

The Safe Home Duo 4 filters are also made to fit very tightly in the filter holder. This unit is also marked so it must be installed so that the air flow goes through the filter in the correct direction. Again it is important that your HVAC technician be aware of this tight fit. These units replace 4 or 5 inch thick filters. Always insert so that airflow goes first through the white side.

Thanks for your question.

Sincerely, Barbara

 

Amaircare Car Air Purifiers Remove Dust, Pollen, Exhaust Fumes, Etc. for Easier Breathing

by Barbara 12. July 2012 10:22

Question about allergy air filters for cars.

Q: "We live in LA. Even with the car windows closed and the AC on, we find our allergies active and the air quality poor. What car air purifiers do you suggest that would thoroughly clean the air in an enclosed car or truck. Thanks. Juli."

Answer; If you want an air filtration system, our suggestions are either of the two Amaircare units described below.

Amaircare XR100 Auto Air Filter Purifier w/12V Plug or the Roomaid Amaircare HEPA Air Purifier in Slate.Concerned about VOC's? Buy the Roomaid in Slate color with optional VOC cartridge. Use in your car or truck with the optional 12 Volt DC Auto Cord Kit for Roomaid Air Purifier The Roomaid also comes in Pure White and in Pure White with VOC Cartridge

The Amaircare XR100 is made especially for use in vehicles. There is an optional AC cord package available. The strong points of this unit include:

  • Three Stage Filtration Process: Air is drawn into the top of the unit and filters through a three-stage filter cartridge. Purified air is then discharged in all directions through the screened opening around the circumference of the unit.

        Stage 1: Large particles, odors: Activated carbon 200% impregnated non-woven, fire retardant, polyester filter media.
        Stage 2: Sub-micron particles: Electret charged filter media attracts and holds sub-micron particles in the air such as dust, pollen, cigarette smoke, bacteria, vehicle emissions, etc.
        Stage 3: V.O.C.'s: Air exits the main filter cartridge and passes through a zeolite impregnated non-woven, polyester filter. This final air filtration stage absorbs additional gaseous contaminants. 
  • Amaircare XR-100 has a high efficiency backward-curved motor/blower for 12 volt or 120 volts use (AC-DC adapter is not included.) Filter rate is 20 cubic feet per minute or 1,200 cubic feet per hour. In the typical car, the hourly air turnover is 1000% or up to ten air exchanges hourly. Better quality air occurs with every cycle.
  • Easy to Install. Takes Up Virtually No Space. The Amaircare XR-100 easily mounts to a car seat back with supplied mounting strap.
  • Easy Plug-in Cigarette Lighter Adapter: Adapter has a seven foot cord.
  • Powerful Motor/Fan: Motors are run tested for 35,000 hours of operation.

There are replacement filters available for both car air filtration units. The main differences are the size, the weight, the number of speeds, and the type of filters used. The Roomaid uses a true HEPA filter plus a VOC filter. The XR-100 uses a three stage media filter with activated carbon, zeolite and an electret charged filter medi. Prices and filter replacement costs, of course, are different as well.

Thank you for your question. Either unit would reduce allergy symptoms and clean the air in your car. We sell more of the XR-100 units for vehicles because they take up less space and hang on the back of a car seat.

Sincerely,

Barbara


 

AirPura Whole House HVAC Air Purifiers, How Do They Differ?

by Barbara 21. May 2011 07:30

Question about the AirPura Whole House forced air heating and cooling system air purifiers.

Q: "I want to install an AirPura HVAC air filtration system. I don't know which one will meet my needs. Please explain what the units have in common and how they differ. Thanks. Sam.

Answer: All the AirPura systems are supplemental air cleaners, i.e. they bypass air from the central air flow, clean it and return it through the main system. All are made in Canada, not China. AirPura suggests you have a "tinsmith" or HVAC person cut the holes in your return air duct. Once connected to your return air duct, a portion of the main airflow is by-passed through the unit which purifies it and returns the clean air into the system. The Airpura unit can continue to filter and distribute clean air throughout your home even when your central air system is turned off. Even when your central air system is turned off the Airpura W600 can continue to filter and distribute clean air throughout your home.

Here are the common features of all AirPura Whole House Air Purifiers:

  • draws a portion of the main airflow as a by-pass, purifies it and returns the clean air into the system.
  • efficient 560 CFM fan motor ensures that no change in air pressure takes place in your central air system.
  • variable speed control, you choose the level of purification required: from OFF to MAX.]
  • save on your energy costs and help protect the environment by cleaning and recirculating your indoor air instead of heating or cooling outdoor air.
  • easy change pre-filter:simply unclip the input pipe and replace the pre-filter pad.
  • 18 lbs Carbon Filter
  • True HEPA filter Traps 99.97% of particles as small as 0.3 microns:40 sq ft HEPA filtration surface
  • Motor and electric parts out of the airflow:Other systems blow clean air over the motor and recontaminate it
  • One piece motor / fan assembly: Eliminates vibration problems where separate fan is attached to a shaft with a set screw. Compact motor / fan design allows more space for filtration
  • Powdercoat steel housing: Robust construction. No plastic vapors.
  • Felt Gaskets Seal the filter chamber: No off gassing from rubber seals
  • Unique pressure seal: The pressure seal system on the filter chamber ensures that all the impurities pass through the filters. Other systems allow dirty air to escape and fail to acheive their promised HEPA rating of 99.97% filtration.
  • Physical Size: 22" high, 15" wide
  • Effective for up to 2000 sq ft

These are the various units and what makes each unique:

  • Airpura R600-W: All Features Listed Above, ie. 18 lb carbon filter plus true HEPA filter. Use in a typical home up to 2000 sq. ft where you want better air quality.

  • Airpura V600-W: All Features Listed Above Plus Enhanced special blend carbon in the 18 lb carbon filter adsorbs VOCs and specific chemicals. True HEPA Filter. Use in a home up to 2000 sq. ft where you have exposure to ammonia, formaldehyde, etc.

  • Airpura UV600-W: UV Germicidal lamp sterilizes antigens, pathogens and mold spores as they are trapped on the filters.17 inches germicidal surface U shaped lamp: 2 times the length of other makes and 2 times as effective Plus 18 lb carbon filter plus true HEPA filter. Use in a home up to 2000 sq. feet. when you are concerned about mold, antigens, germs, etc.
  • Airpura P600-W:  TitanClean photocatalytic oxidizion technology targets VOCs, airborne chemicals and odors as well as mold, particles and microorganisms. Has a titanium dioxide reflector that works in conjunction with the Airpura'20 watt UV germicidal lamp. 18 lb. carbon filter, true HEPA filter. Use in home or business up to 2000 sq. ft. when you are concerned about reducing airborne chemicals to smaller safer compounds, until only carbon dioxide and water vapor are left. You can retrofit your UV600-W (a portable air cleaner) to use this reflector.
  • Airpura H600-W:  For allergy and asthma sufferers and full scale particle filtration. Hi-C carbon weave filter traps airborne chemicals and odors. 18 lb. carbon filter, True HEPA Filter. Use in a home up to 2000 sq. ft. where persons live with allergies to pollen, dust mites, dust, etc. as well as to chemical odors.
  • Airpura C600-W:  Extra large carbon bed ( 3 Inch) for maximum carbon adsorbtion. Especially effective for airborne chemicals and gases. 26 lb. carbon filter.  Special carbon blends available for specific chemical problems. HEPA-Barrier post filter traps particles. True HEPA Filter. For house or building up to 2000 sq. ft with HVAC forced air heating and air conditioning system.

So choose an AirPura whole house unit based upon your needs. Remember that if you have a house larger than 2000 sq. ft, the effectiveness of any of these units is greatly reduced. In many homes larger than 2000 sq. ft, there are 2 or more HVAC units depending upon the home size.

I hope this has helped you to make your decision. Thanks for your question.

Sincerely, Barbara

 

Ultra Low Resistance Allergen Filters for Cold Air Return Filter Grilles in Walls or Ceilings

by Barbara 22. August 2010 06:01

Question about theSafeHome Duo 20 inch by 20 inch by 1 inch 4 Pack and the Safe Home System Cold Air Return Purifier, 16X20X1

Q: "What is the difference between the two units as far as air flow and filtration is concerned? I manage a clinic where we have several very large cold air filter grills. Some physicians use aerosol products during medical treatments. We are also concerns about keeping the level of dust, spores, etc. to a minimum as the forced air HVAC system recirculates air. The filter grilles are hinged. Currently we are using 1 inch fiberglass disposable filters. Thank you for your input. Steve."

Answer: Both types of air filters will fit your 16 x 20 x 1 inch air return filter grille.

The Safe Home Duo, is a two layered polyester filter with a MERV8 rating. The first layer filters the particulates like dust, pollen, etc. The second, inner layer is impregnated with carbon and potassium permanganate that is for chemical removal.The Duo offers the same allergen, odor and chemical removal as the System, but in a single 1" filter. Duos utilize an inner steel frame that creates a filter with self sealing edges for great filtration and whisper quiet operation. SafeHome Duos are available as individual 3 month filters. You may need to replace more often depending upon your facility. To install, you fold the excess material around the filter's internal frame to slide it into the grille and then tuck the remainder in so you can close the cover over the filter slot. This excess material helps seal the edges where the filter fits into the equipment and keeps air from going around the filter through gaps. Air should enter the white side, which traps allergens, and exit through the dark side, which traps gases and odors.

The SafeHome System Annual filter package consists of four pre-filters for dust, pollen, spores, etc. and one pollution filter. The pollution filter absorbs gases and odors and fits into the air duct behind the return grille with filter slot. The System has 125 grams per square foot of activated carbon and FormadaSorb to remove the most common, hazardous pollutants. The replacement filters for the filter slot are electrostatic air purifier filters. These pre-filters should be changed at least every three months.

More frequent changes may be necessary due to a wide variety of circumstances that increase chemical, odors and particles like allergens or dust. Examples of chemical and particulate sources include the following:

  • Painting or renovations
  • High levels of outdoor pollution
  • Burning candles or using air deodorizers
  • Cleaning agents
  • Shedding Pets
  • High activity levels

Rated at MERV 7, these filters are pleated with thin metal wire in diamond shapes covering the pleats. MERV 7 is an industry standard rating that means the filter removes 50% to 70% of particles down to 3 microns in size. With use, removal increases to more than 98% effectiveness.

The manufacturer recommends that the Safe Home System be used in the largest air return grill for each air system. So, one choice is to use the Duo filters in all but the largest air return grill. When you calculate the difference in price, however, you may elect to keep all the grille filters the same especially if they are the same size in each exam or waiting room.

Both the SafeHome Duo and the SafeHome System come in many sizes.

Thank you for your question. Please contact us if you need more information.

Sincerely, Barbara
