Spa Ozonators

Reduce chemical use and improve water quality in your hot tub or spa with ozone generators from Ultra Pure and Del Advanced Sanitizer Solutions. PST Pool Supplies stocks UV and corona discharge ozonators for residential portable spas and in-ground pool spas — starting from $137.80.

Ozone (O₃) is one of the most powerful oxidizers and sanitizers available for water treatment — up to 3,000 times more effective than chlorine at killing pathogens. A spa ozonator continuously generates ozone that is injected into the circulation system, oxidizing contaminants, killing bacteria, and breaking down chloramines, allowing the spa to maintain sanitation at dramatically lower chemical concentrations. The key units in this collection: the Ultra Pure BFO3 (115V, NEMA plug, UV type) is the entry-level UV ozonator — a plug-in unit suitable for portable spas up to approximately 600 gallons, using UV-C lamp technology with a NEMA 5-15 standard outlet connection. The Ultra Pure UPS350 (115V, 4-pin AMP cord) is a UV ozonator with a 4-pin AMP connector for direct integration with Balboa, Hydro-Quip, and other spa control systems that have a dedicated ozonator port — no separate outlet required. The Ultra Pure EUV3 (115V/230V, 1/4\" female disconnects) is a dual-voltage UV ozonator with universal wiring terminations for custom installations. The DEL Eclipse CD ozonators use corona discharge technology: the EC-10 (12W, up to 25,000 gallons) and EC-20 (24W, up to 50,000 gallons) are high-output units for larger spas and commercial applications — both operate on 115V/230V. The DEL Ozone AOP 25 combines corona discharge ozone with UV-C in an advanced oxidation process (AOP) system for pools up to 25,000 gallons — the most comprehensive chemical reduction system in this collection.

When selecting a spa ozonator: match the unit's capacity to your spa volume (most portable residential spas are 300–600 gallons; UV ozonators are adequate for this range), confirm the electrical connection type (NEMA plug, AMP connector, or hardwired disconnects), and ensure a check valve is installed in the ozone line. Always pair a new ozonator with a new check valve and fresh ozone-rated tubing for maximum system longevity.

Shop spa ozonators at PST Pool Supplies and give your hot tub a cleaner, softer water experience with significantly less chemical maintenance.

Frequently Asked Questions

How much can a spa ozonator reduce my chemical costs?
A properly functioning spa ozonator typically reduces sanitizer consumption by 50–75% compared to a conventionally sanitized spa. Instead of maintaining 3–5 ppm free chlorine (or bromine equivalent), a spa with an ozonator needs only 0.5–1.0 ppm free chlorine as a residual backup. Ozone handles the heavy oxidation load — breaking down organic contaminants, killing pathogens, and destroying chloramines — that would otherwise require large doses of chlorine shock. In practical terms: a spa owner spending $30–$50/month on chlorine and shock may spend $8–$15/month with an ozonator doing the primary oxidation work. Additional benefits beyond chemical cost: (1) Longer water change intervals — ozone breaks down total dissolved solids more effectively, extending the time between full spa drains. (2) Reduced chloramine formation — less combined chlorine means less skin and eye irritation. (3) Cleaner equipment — ozone prevents biofilm growth in plumbing, jets, and heater manifolds. The ozonator pays for itself in chemical savings within 1–2 seasons for most spa owners.
How do I choose between a UV ozonator and a corona discharge ozonator for my spa?
For most residential portable spas (300–600 gallons), a UV ozonator (Ultra Pure BFO3, UPS350, or EUV3) is the appropriate choice — it produces sufficient ozone for a small water volume, is less expensive, and simpler to install and maintain. UV ozonators require bulb replacement every 12–24 months (approximately $47 for the UP350/EUV3 bulb) but have no high-voltage components. Choose a corona discharge ozonator (DEL Eclipse EC-10 or EC-20) when: (1) Your spa is larger than 600 gallons. (2) You have a swim spa (1,000–2,000 gallons). (3) You want maximum chemical reduction and are willing to invest more upfront. (4) You have a commercial application. CD ozonators cost significantly more but produce 5–10x more ozone per watt than UV units, and the CD cell lasts 3–5 years without replacement. The CD cell is, however, immediately destroyed by water intrusion — a check valve failure on a CD ozonator results in an expensive repair. For the connection type: if your spa control board has a dedicated ozonator port (4-pin AMP or similar), select the UPS350 or EUV3 with matching connector. If your spa lacks an ozonator port, the BFO3 with NEMA plug connects to any standard outlet.
Is ozone safe for spa bathers?
Ozone is safe when the spa ozonator system is properly installed and functioning correctly. The key safety principle: ozone must be fully consumed in the water before bathers enter. In a properly designed spa ozonator system, ozone is injected into the circulation return line well before the water re-enters the spa — the ozone reacts completely with contaminants in the plumbing before reaching the spa shell. By the time ozonated water enters the spa, the dissolved ozone concentration is essentially zero. Off-gassing (ozone escaping into the air above the spa) can occur if the ozone injection point is too close to the return jets or if the ozonator output exceeds what the water can absorb. Signs of excess off-gassing: a sharp chemical smell near the spa surface, eye irritation when leaning over the spa. Solutions: reduce ozonator run time, move the injection point farther from the return jets, or install an ozone destruct unit on the ozone line. At the ozone concentrations generated by residential spa ozonators, properly installed systems pose no health risk to bathers — the EPA and NSF both recognize ozone as a safe and effective water treatment technology for residential and commercial aquatics.
What connection type does my spa use for an ozonator?
Spa ozonator connections vary by control system manufacturer: (1) 4-pin AMP connector — the most common connection for integrated ozonator ports on Balboa, Hydro-Quip, and many other residential spa control systems. The Ultra Pure UPS350 uses this connector. The 4-pin AMP plug provides both power and a signal connection to the control board. (2) NEMA 5-15 outlet (standard household plug) — some spa control systems include a switched 120V outlet for the ozonator. The Ultra Pure BFO3 connects via standard NEMA plug to this outlet. (3) 1/4" female disconnects (spade terminals) — used in hardwired ozonator installations where the installer connects the wires directly to the spa's power distribution. The Ultra Pure EUV3 uses this connection. (4) No dedicated connection — some older spas have no ozonator port at all; an ozonator can be added by connecting to the spa's 120V power supply with proper GFCI protection. To confirm your connection type: look for a labeled ozonator port on the spa control board (usually labeled OZ, OZONE, or O3), check the existing ozonator's plug style if replacing a unit, or consult your spa's wiring diagram. If uncertain, the BFO3 NEMA plug version is the most universally compatible option.
