Windmill Air (windmillair.com) is a New York-based modern air care brand founded in 2020 by brothers Mike Mayer and Danny Mayer, alongside third-generation AC industry expert Ryan Figlia, with a singular mission: to modernize home air and comfort from the ground up. The brand launched with a radical rethink of the window air conditioner — one of the most universally disliked household appliances — and quickly became a viral hit on social media for doing something the category had never managed: making a window AC unit genuinely attractive. Publications and reviewers have called Windmill the "iPhone of Air Conditioning," a comparison that captures both the design philosophy and the software-first approach that separates it from every traditional AC brand in the market.

In just five years, Windmill Air has sold more than 100,000 AC units across the United States, secured product placements in major national retailers including Home Depot, Best Buy, Lowe's, P.C. Richard & Son, and Wayfair, raised a $5M Series A funding round backed by YETI Capital, Pentland Ventures, Dot Capital, and SuperAngel.Fund, and expanded its product lineup well beyond its original window AC to include a next-generation Air Purifier, an Air Circulator and Fan, and a digital-first central air filter subscription. The brand is family-run and built on more than 60 years of combined air care expertise — a heritage that shows in the engineering decisions behind every product Windmill ships.

The Windmill AC Product Lineup

Windmill currently offers five window AC configurations spanning two technology tiers — the Original series and the WhisperTech™ Inverter series — covering rooms from approximately 250 to 550 square feet:

The Original AC (6,000 BTU) is the entry point to the Windmill lineup and the product that launched the brand. Designed for rooms up to approximately 250 square feet, the Original AC delivers Windmill's signature curved-edge, low-profile design alongside app and voice control, 3 cooling settings, 3 fan speeds, auto-dimming LED display, double-insulating side panels, and a dual-filtration system with a washable mesh filter. At 49 dB in operation, it is quieter than traditional window units and installs without tools using a pre-assembled kit.

The Original AC (8,000 BTU) scales the same Original-series feature set up to rooms of approximately 350 square feet.

The WhisperTech™ AC (8,000 BTU) is where Windmill's engineering genuinely separates itself from every other window AC on the market. WhisperTech uses a variable-speed inverter compressor combined with a near-silent linear fan and a dual air intake design that pulls air from both the front and the bottom of the unit, delivering cooling upward and outward at a 45° angle for even room-wide comfort without cold spots or direct blasts. The result is operation at approximately 42 dB — 9 times quieter than industry-average non-inverter units — and energy savings of up to 40% compared to standard fixed-speed compressor ACs. EER ratings across WhisperTech models run between 11.4 and 11.8, and select models carry Energy Star certification. Covers rooms up to approximately 350 square feet.

The WhisperTech™ AC (10,000 BTU) brings inverter performance to rooms up to approximately 450 square feet — the ideal configuration for larger living rooms, open-plan apartments, or spaces that run warm.

The WhisperTech™ AC (12,000 BTU) is Windmill's largest and most powerful model, covering rooms up to approximately 550 square feet. Designed for renters and homeowners with larger spaces who want inverter efficiency, voice control, and Windmill's design aesthetic in a single unit.

All Windmill ACs ship with a pre-assembled installation kit that requires no tools, an auto-dimming LED display that fades after 60 seconds to eliminate blue light disruption during sleep, a magnetic removable front panel that allows customers to swap in decorative color options (Lavender, Sky Blue, Sunset), and full Wi-Fi connectivity with the Windmill Air mobile app, Alexa, and Google Assistant. The app enables remote control from anywhere, smart scheduling, geofencing (automatic shutoff when you leave, automatic startup when you return), and eco mode for passive energy management.

The Windmill Air Purifier

Launched in October 2024, the Windmill Air Purifier entered a category the brand described as long overdue for a design and performance upgrade — with most purifiers on the market being unsightly, noisy, and underperforming relative to their price. Built with the same minimalist design philosophy that defined the original AC, the Windmill Air Purifier combines HEPA filtration technology with the brand's signature app control and contemporary aesthetic. Prices start at $299 at windmillair.com.

The Windmill Air Circulator and Fan

Launched in early 2024, the Windmill Air Circulator and Fan was designed with 5 speeds to function as both a personal/desk fan on low settings (Whisper mode runs under 19 dB) and as a whole-room air circulator on High and Boost settings (over 380 CFM). It is 29% more powerful, 25% smaller, and 20% quieter than comparable traditional fans. Windmill specifically designed this product as a companion to their AC units — using a fan alongside an AC on lower cooling settings can reduce energy demand by up to 76%, according to research cited by the brand.

Accessories and Central Air Filters

Windmill also sells a range of accessories including Activated Carbon Filters (a four-pack at $45.24), washable Mesh Filters, decorative Front Panels, and Winter Covers. For customers with central air systems, Windmill offers a digital-first central air filter subscription — a category the brand entered early in its growth and that reflects its ambition to cover the full home air care ecosystem rather than just the window AC segment.

Retail and Smart Home Ecosystem

Windmill AC units are available directly at windmillair.com and through Home Depot, Best Buy, Lowe's, P.C. Richard & Son, and Wayfair.
