What Is a High Efficiency Air Filter?

Friday, February 27th, 2015

Having good indoor air quality is important to your year-round, overall comfort. One way to help ensure that your indoor air quality is at the level you need and want it to be is by using a high efficiency air filter, also known as a HEPA filter, in your Springfield, PA, home. However, before installing any kind of HEPA filter into your HVAC system, it’s very important to consult with an indoor air quality expert. This is because the media in a HEPA filter can be so strong that it significantly reduces the air flow in your HVAC system, which can lead to operational problems. Wm. Henderson Plumbing & Heating Inc., has been providing indoor air quality services for almost 40 years, and our IAQ specialists can help you determine which HEPA filter is best for your home. Call us today!


MERV and HEPA are intertwined because MERV, which stands for minimum efficiency reporting value, tells consumers how effective a particular air filter is. The MERV scale runs from 1 to 20, and to qualify as a HEPA filter, the filter has to have a minimum MERV of 13 and these other qualifications:

  • The filter must be able to trap particles as small as 3 microns (human hair is typically 70-100 microns in size)
  • The filter must be tested according to US Military standard 282, and each tested filter must be individually certified and labeled with its test results
  • The filter must have a minimum efficiency rating of 99.97%


What Makes a HEPA Filter Different?

One of the main differences between HEPA mechanical filters and those that aren’t HEPA is the capture capability. HEPA filters are made to capture a great many particles, including some biological contaminants. This is because of how they are made, which brings us to a second difference between HEPA filters and non-HEPA filters. The media of HEPA filters is made with a glass-fiber type of paper that is highly effective at capturing particles. This paper is folded into small V-shaped pleats that are held firmly in place by aluminum separators between each pleat. Pleating makes it difficult for particles to continue passing through filter media, which is part of the reason why HEPA filters are so effective.

As mentioned above, HEPA filters should only be installed into your HVAC system after working with a qualified specialist. If you feel a high efficiency air filter in Springfield, PA is for you, call the indoor air quality experts at Wm. Henderson Plumbing & Heating Inc., today!

Signs Your Commercial Plumbing Needs Replacement

Friday, February 20th, 2015

No business owner wants to think about having to replace plumbing, but as a business owner, you could be at serious risk of rendering your commercial space unusable if you don’t make needed plumbing replacement or repairs. Commercial plumbing systems are long and complex, so it’s important to hire experts with experience in commercial plumbing replacement for your Bryn Mawr business. Wm. Henderson Plumbing & Heating Inc., has been helping commercial customers with their plumbing needs since 1977, so if you are experiencing problems with your commercial plumbing, call us today!

Seeing the Signs

Here are some of the more common signs that you may need to replace the plumbing in your commercial space:

Discolored Water

Discolored water is often a sign that rust or excessive dirt is inside your piping. Typically discoloration will be brown or yellow, but any kind of discoloration means a problem has developed with your system and professional assistance is required.

Recurring or Multiple Leaks

If you have a leak that keeps coming back, or have been dealing with multiple leaks developing throughout your system, it’s time to have a professional assess the situation as it may be time to replace damaged piping.

Flaking or Dimpling of Metal Pipes

If you can see visible flaking or dimpling of your commercial space’s piping, there is excessive corrosion both in- and outside the piping. Excessive corrosion in any plumbing system is a serious problem and should be addressed immediately.

Development of Mold

Mold needs moisture to grow, so if you are seeing a lot of mold in a particular area or smelling a strong odor of mold, it is likely you have a leak on your hands; as such, you may need to replace the piping that is the origination of the leak, depending on the level of damage.

Water Pressure Problems

Water pressure is necessary for your plumbing to work, but if the pressure is too high or too low, a number of different types of problems can develop.

For your business space to be operable, it needs proper water function. If you are seeing the signs that it may be time for commercial plumbing replacement in Bryn Mawr, call the commercial plumbing experts you can count on: Wm. Henderson Plumbing & Heating Inc.

Some of the Unusual Movies Released for Valentine’s Day

Saturday, February 14th, 2015

Hollywood has always tried to match movies up to the seasons to draw droves of viewers to the theaters: October is packed with fright-offerings, while the winter holidays skew toward warm and pleasing family films (as well as Oscar hopefuls). Valentine’s Day falls in an odd spot when it comes to the movie release calendar, however, since February tends to be a slower time for the film industry. The studios are as likely to slot strange movies that don’t fit anywhere else in their annual schedules into the Valentine’s Day weekend as they are films with powerful romantic appeal.

So, while the second weekend of February has featured hugely successful romantic comedies like Hitch, The Wedding Singer, and (of course) Valentine’s Day, some truly weird choices have debuted in this weekend as well. And a few have even gone on to tremendous success despite the bizarre match with the holiday. Here are a couple of the odder Valentine’s Day movie releases:

  • Dracula (1931): Yes, this Halloween perennial and the start of Universal Studio’s Classic Monsters actually came out on Valentine’s Day! But perhaps this makes some sense, as the Dracula legend has often received a “doomed lover” approach in the many years since Bela Lugosi made the aristocratic vampire a screen icon.
  • The Silence of the Lambs (1991): Does any film seem less appropriate for Valentine’s Day than this unnerving and sometimes very violent psychological thriller? What’s even more astonishing than the film’s release date is that The Silence of the Lambs eventually nabbed the Oscar for Best Picture, an almost unheard of occurrence for a movie released so early in the year.
  • Daredevil (2003): This Marvel comic adaptation featuring Ben Affleck as a blind superhero does contain a romantic subplot, but the stronger connection to Valentine’s Day may just be that Daredevil wears a bright red costume.
  • A Good Day to Die Hard (2013): The least successful of the Die Hard film franchise, this is an excellent example of a studio dropping a film into a weekend where it doesn’t fit in the hopes that it works as counter-programming. (It didn’t.)
  • Wayne’s World (1992): Now here is an example of counter-programming that clicked with audiences. This comedy based on a Saturday Night Live sketch turned into one of that year’s biggest hits and spawned a sequel.

Whether you celebrate Valentine’s Day with a trip to the movie theater, or you have your own special plans, everyone here at WM Henderson Inc. hopes you and your loved ones have a wonderful weekend.

How Can Drain Cleaning Help Prevent Drain Repair?

Thursday, February 5th, 2015

While very few people truly enjoy cleaning the bathroom, you try to keep it as clean as possible for your guests and your own health and comfort. But while you may scrub the toilet, tub, and sinks diligently, there’s still one portion you may always miss, the drains. The drain opening may be shiny and spotless, but the inside of the drains in the bathroom and the kitchen may be coated with grease, “sludge,” and a bit of debris here and there. This increases the potential for drain clogs, which can inconvenience you in some major ways.

Some people attempt drain cleaning on their own as a form of clog removal or drain maintenance by pouring drain cleaning liquids down the drain. These are generally found at most hardware shops and even many grocery stores, but beware: these are some of the most toxic chemicals available for consumers to purchase in stores. Furthermore, they can actually damage the pipes, and most don’t clear clogs completely.

Professional drain cleaning uses zero toxic chemicals, so that no damage is accrued. Instead, they use any of several tools including drain augers that reach deep into the drain pipes and latch onto clogs in order to pull them up through the drain. Or, a technician may use a different attachment to break up clogs and send them into the sewer. In some cases, technicians may have to use high-pressure hoses to blast water into the pipes and remove any stuck-on sludge.

Some experts even use video pipes to inspect deep within the pipes and make sure that clogs are completely taken care of and that no further problems may lead to clogging in the future. Drain cleaning is a service which can vastly improve the condition of your plumbing system, to the point that you’re unlikely to run into any major drain clogs for the rest of the year.
