HH1506 Standard Bag
Everyday use - Best for larger debris and coarser sand and dust particles.
About our bags
Authentic Hammer-Head debris bags are hand made here in the USA and are inspected prior to packaging and shipment. Each bag has a tag with the Hammer-Head name that indicates what type it is.
We warranty them against defects in workmanship but not against wear and tear. Treat your debris bags with care. Dragging them on the bottom of the pool, the deck, or across the coping when lifting them out of the water can wear holes in them. Empty them frequently while vacuuming, and store them clean, dry, and out of the sunlight for the longest life.
About Bag Size
XL bags are approximately two times the capacity of our normal bag and measure about 48" in length. A normal standard, superfine or coarse bag is about 24".
About Micron Ratings
A micron is one millionth of a meter, or approximately .00003937 inches. The smaller the micron number, the finer the bag. As debris goes, anything below about 40 microns is smaller than the human eye can easily see. White blood cells are about 25 microns, red blood cells are 8 and bacteria generally around 2 microns.
The true test of a bag is how it works for you
You can't see a micron with the naked eye, but filtration is measured, talked about and bragged about in microns. So what is a micron anyway?
A micron is one millionth of a meter, or approximately .00003937 inches. Micron ratings are also absolute or nominal. Absolute micron ratings mean that the filter media will filter out 90% of particles below that micron size. Nominal micron ratings mean that the filter media will retain particles but not to any percentage greater than 50%.
To put it simply, the smaller the micron number, the finer the bag. As debris goes, any particle below about 40 microns is smaller than the human eye can easily see.
Average diameter of a human hair: 70 microns
White blood cells: 25 microns
Talcum powder: 10 microns
Red blood cells: 8 microns
Bacteria: 2 microns
What does this mean? When a filter or bag manufacturer claims they have a 3 or 6 micron rating, you should ask yourself: Will this really filter blood cells, or actual bacteria? We don't think so either.
The truth is, there isn't much truth to micron ratings because there is no standardized testing for these ratings. Each manufacturer can apply any rating based on their own testing. Take a look at this chart to see some examples:
||White blood cells?
(at the bottom end of the filtration spectrum, we doubt it)
(we've seen cartridge filters pass DE)
(maybe, but do you remember looking at bacteria cells under a microscope in school?
What is really important to you, the service manager or maintenance technician, is the real-world performance of these filter media, and of course, the Hammer-Head debris bags. Hammer-Head bags are so popular, they are even used by owners of other vacuums.
The bottom line: Don't believe every micron claim you read. With no industry standard, the only true test is the real-world test you perform yourself.
