About the new Health Water filter and the old HW series:The HW series (HW-302, 303 and 304) are currently the best-selling outdoor filters not only in Poland. They owe their popularity to their low price combined with good quality and very high capacity. Now the manufacturer SunSun is introducing a new series of Health Water filters (702, 703 and 704) as an upgrade of the earlier HW. The filters are based on proven technology and a design proven over the years and hundreds of thousands of users. The new HWs still provide outstanding filtration through their large capacity, but their design has been improved and the filter motor has been modified. Read about the differences in the following paragraph:What's new? What are the differences between the new and the old HW?Already at first contact, you will notice a considerable difference in the appearance of the filter. The new external shape is the result of the following design changes: - guides.That is , you will always close the filter correctly again.The possibility of the filter leaking on the main seal, which was caused by the angled position of the lid, has been eliminated. That is, the possibility of closing the filter at a deviation from the correct radius in a horizontal plane. The new filter has special guides to ensure that the filter is closed in the correct alignment. So, the most common leakage problem, which was basically user error, has been eliminated. - Double bucket. Reinforced walls.The main bucket, in other words the container for the filter media, has reinforcing columns. This solution has its motives, as it provides adequate structural rigidity and strength. In addition, it dampens vibrations well by suppressing the sound of the filter's operation.- stop the bubbling! Bubbles are only good in champagne.Over 90% of bucket filters have a hand pump design that is not quite right. By design, it is responsible for priming the filter and hoses and is supposed to be used to bleed the filter. Often it is the culprit for the filter's aeration. It is literally the place where air is held in. This leads to an obstruction and manifests itself in the constant spitting out of air. Pumping or shaking the filter doesn't help much and it can even last for days. Horror!New Health Water has avoided this problem through water flow channels and a different impeller placement. The air bubble no longer has its 'safe' place and is 'spit' out of place by the filter. - New energy-efficient motorEnergy consumption has been reduced by 22%. This is good news with ever-increasing electricity prices. Annually, you will save up to 60 PLN on electricity alone! - new inlet and outletThis element has also been modernised. Both the inlet and outlet have been fitted with a holder for the edge of the aquarium. Hose suction cups and hose clamps are also included, guaranteeing the durability of the installationInlet: has modules, increasing the length of the tube. Lengths from 15 to 60cm. Outlet: Rain shower. Has modules. Length from 20 to 40 cm. The outlet is rotatable.- UV lamp auto-off switchThere is a clever device in the filter housing. Namely an auto-off switch for the UV lamp. This will switch off the UV filament automatically, protecting your eyes and your health, should you wish to run the lamp on an open filter.A large filter means better filtration."This has always been obvious to those who have studied aquaristics." It is not the brand, the price or the manufacturer's accolades that make a filter good. The rule is simple: the more cartridges the better the filter. It is worth noting that HW filters are some of the biggest on the market. Most manufacturers only increase the power of the pump which misses the point, but looks better on the poplar and convinces uninformed customers. The filter is supposed to filter through the filter cartridges! And the pump power is supposed to be adjusted accordingly. Too high a water flow will literally flush through the filter, leaving no opportunity for mechanical, biological or chemical filtering. Sterilisationby UV-C lamp:Waves of UV-C light quickly and effectively sterilise the water. That is, they instantly kill all kinds of algae and algal spores, viruses, fungi, cyanobacteria (blue-green algae) and other unwanted microorganisms. Daily use of the UV lamp prevents algae infestations and various other unwanted surprises. The lamp has a separate on/off switch for use when needed or according to an established prevention schedule. There is a viewfinder in the housing to indicate the operation of the filament.All Health Water filters are tested before sale. The proof? Residual water under the lid. You are not buying blind. New developments introduced, proven technology, low power consumption, pre-sale testing and low prices.
