Air purifiers use a variety of methods to clean the air in your home, office, or commercial building. Most manufacturers claim their technology is superior, but how effective is it? This section explores the major technology used in air purifier products today and how effective it is at cleaning the air. We cite expert sources like the Environmental Protection Agency to provide trusted answers and help you find products that really work.

Most of today's hot tubs are ozone-ready, so adding or replacing one is a snap! Some spas take a bit more effort.. we'll show you how. You'll save a bundle when your buy your ozonator from The Spa Depot, where quality comes at a fair price.

Ozonators convert oxygen into ozone. A clear air line from the ozone generator is connected to your spa's plumbing system. The flow created by the pump creates a Venturi suction, which draws the ozone into the spa water where it dissolves.  maier air purifier priceThe ozonator itself is connected to your spa control system, which supplies power and regulates its cycles of operation.bwell air purifier CD Ozonator Kit from AquaSunwinix air purifier 9000 Step-by-step instructions are provided with every spa ozonator kit we sell, to make installation easy. Advanced CD ozonators such as Aqua Sun have special technology which greatly increases life expectancy and output compared to older UV designs.

We'll explain the different installation schemes below. Regardless of the type of ozonator installation, the first step (after disconnecting the electrical power) is to remove the spa's access panel. Identified here in the hot tub's equipment bay: Spa's ozone-ready suction connection Installation in an Ozone-Ready Spa Ozone-ready spas usually have a small ozone jet near the bottom of the spa. This jet will have a water port, and an air (ozone) port. When no ozonator is present, the jet acts as a water jet only. A clear 1/4" I.D. air suction tube from this jet, with the end capped-off, should be hanging in the equipment bay, if no ozonator has been installed. Locate the ozone suction connection as illustrated (2). This is typically 1/4" I.D. x 3/8" O.D. vinyl air tubing. In this case, the tubing has a cap, which is snipped off to accommodate the one-way check valve included in the ozonator kit. This valve helps prevent water from accidentally entering the ozonator.

Attach the ozone check valve to one end of the vinyl tubing supplied with your ozonator kit. The other end of the check valve attaches to the spa's suction tubing ( fig. 2). The air (ozone) flow direction is away from the ozonator and toward the spa. The valve may be marked as to direction. If not marked, you can determine the flow direction by blowing into one end of the valve. Installing the check valve backward will prevent functionality, so this is important. Jet Water Line Connection Method A simple way to hook up the line is to use an ozone injector, which is a Venturi placed into a jet water line, typically 3/4" I.D. tubing. The water flow provides suction which draws ozone into the spa. This method is very effective for ozone dispersion. Select a jet as near the bottom of the spa as possible, for maximum water contact. Make sure to observe the flow orientation, as noted on the injector. The ozone line should be double-looped above the water line (called a Hartford loop) and the supplied air check valve installed to help prevent water intrusion into the ozonator.

Tip: Dissolving Ozone More Effectively You can achieve optimum ozone effectiveness by adding our Ozone Turbo Mixer which increases the amount of ozone which dissolves in the water by up to 45%. This greatly compensates for a lack of contact time of the gas to water, especially in tubing runs from the Injector to the ozone wall jet which are not long enough to fully dissolve the ozone gas prior to introduction into the spa vessel. Note: Turbo MIxer is not needed for XL-80 model (below). Our new AquaSun XL-80 Ozone System is even simpler to install. It is the only ozonator with a built-in Venturi injector and a built-in cavity mixer. The unit even has an internal check valve. Since there's no air line to hook up, installation could not be easier. The XL-80 even auto-detects and adapts to either 120V or 240V power! Main Water Line Connection Method If jet water line access is impractical because your spa is full-foamed or lines are inaccessible, another excellent method is to install an ozone injector manifold into the main water line.

This line is the hot tub's large plumbing, typically 1-1/2" or 2" I.D. flex pipe. The manifold employs a bypass valve design to prevent drastic reduction of jet pressure and strain on the pump that would result by placing an injector directly into this line. This is also the preferred system for installing an ozonator on an in-ground spa. (location of filter may vary) The injector creates a suction which pulls ozone from the ozonator, mixes it with water, and delivers it to the spa jets very efficiently. It is important to install the ozone Injector Manifold the hot tub heater, pump and filter, to avoid possible damage to those components which could be caused by a high direct concentration of un-dissolved ozone. After installation of the Injector Manifold, the ozonator output line is connected to the injector suction bib fitting, as shown above. To prevent water from backing-up into the ozonator, a check valve should be installed. The ozonator output line should also be looped high in the spa cabinet (above water level).

This is called a Hartford Loop, and provides additional protection from water back flow. You can connect your ozonator's air (ozone) line directly to one of your hot tub jet's air orifices, if you can access it. Select a jet that is low in the water for maximum ozone dispersion. Some hot tub jets are fed by a manifold with separate air lines to each jet, while other designs use looped jetting with air going into one side of a jet and out to the next jet, and so on, with each jet having two air connections. Air Induction System Connection Method This is an alternate method for installing an ozonator into a spa's air induction control system. Although this method will work, it is not nearly as reliable in dissolving ozone into the water as the previous methods listed. If your spa has topside air controls, you have an air induction system. If you can access these parts, you can use this method for installing the ozonator's air (ozone) line. Note: When the spa's air control valve is in the open position (no air to jets) little suction will be produced, and therefore little ozone induced into your spa water.

The air valves must be in sound condition, allowing all air induction to the hot tub to be shut off or on, in order for this method to work reliably. Most of today's spa packs or control systems, located in the spa's equipment cabinet, will have an ozone receptacle to supply power to the ozonator, and control its cycle. There are many plug types used for various hot tub makes, the 4-prong Amp style being the most common. Safety Precautions & Recommendations: Turn off hot tub power at source breaker before installing or servicing ozonators. Disconnect the spa's power cable as an additional secondary precaution. All applicable electrical codes must be followed during and after installation. All connections to be made by a qualified electrician. Electrical installations carry the risk of electric shock. Connect only to a properly grounded, GFCI-protected power source. Do not bury cord. The ozone generator is to be located with a looped supply hose (Hartford loop) above the water level.
