The Newest Must-Have Home Amenity for the Rich: Purified Air
Pollution, allergens and Covid have homeowners focusing on filtration systems and flexible designs to improve indoor air quality

Visitors to John Bautista and Pedro Salrach’s San Francisco home can’t get enough of the lap pool, sauna and movie theatre. But they also get a whiff of something else they value: clean air.
“The house smells new—and after two years it still smells new,” said Bautista, an attorney. “I know when I’m home because it smells clean and fresh.”

The six-bedroom home with seven bathrooms and two half-baths includes an elaborate air-filtration system meant to deal with the region’s varying air quality. The tightly sealed floor-to-ceiling windows and sliding doors offer hilltop views of the bay and access to the backyard without sacrificing air quality.
Bautista plans to further upgrade his system this year with the aim of filtering and recirculating indoor air rather than fresh outside air during periods of heavy pollution. Despite the home’s superior air quality, the family can still feel a difference on days when the outdoor air is filled with smoke. “We’ve suffered, as most people have in the Bay Area,” he said. “What we want to have is isolation.”
Developer Gregory Malin, who specialises in wellness-focused real estate, sold Bautista the home for $32 million, he said, plus an additional $5 million for fixtures and furnishings.
Luxury homeowners are known to splurge on sleek kitchens, custom decor and art, but they are increasingly turning their attention to something less visible. Forest-fire smoke, the pandemic and increased awareness of sensitivities to mould and other irritants are making their interior environment a priority.
Many are investing in complex systems and flexible designs that promise healthier indoor air but still include spaces, such as glass-enclosed rooms, that make being indoors feel natural.
Listings are increasingly touting pollution-fighting amenities to lure home buyers. In Santa Rosa, Calif., a 13-acre estate for sale at $15 million has a whole-home air purifier. This spring, the Dovecote building, under construction in Manhattan’s Harlem neighbourhood, will offer six, three-bedroom condos built to strict green and clean-air standards, starting at $1.5 million.
Malin, founder of Troon Pacific, a San Francisco-based developer of $15 million to $45 million properties that he calls healthy homes, said he focuses on the smallest details that can affect air quality. New tools allow for more-precise measurement of various particulate matter and carbon dioxide levels, he added. “Covid changed people’s perspective on connecting air quality to health, and the [wildfires] only enhanced that.”
His company’s newer homes have exhaust fans, tied to ventilation systems, in laundry rooms and under sinks, where there are various pollutants and harmful cleaning products, said Malin. Their garages have separate exhaust fans that go on long enough for three air exchanges after the door opens. Ionisation-based filtration systems also are included to eliminate airborne particles too tiny to see but hazardous when inhaled.
His homes also feature perforated piping with in-line fans to exhaust air from under slab foundations to keep contaminated soil vapours from entering the houses.
He said his company is considering building to the Living Building Challenge standard, in which homes have their own electricity, water and waste management. Demand is high for such standards, he said, including passive-home construction, where airtight homes are built using specific materials and energy-efficient systems that circulate highly filtered air. He said passive-home certification is costly, especially for big homes, and has limitations that some homeowners don’t want, like bulky windows. In the long run, however, he said eliminating most heating and cooling bills is probably worth it.

Clean air has become more of a talking point in homeownership, added Elliott Gall, an associate professor of mechanical and materials engineering who researches indoor-air quality at Portland State University.
While high-rises are often built to be airtight, there is a greater focus now on having windows that open while adding better filtration systems, he said. Units with outdoor access sometimes give homeowners another way to control the humidity and indoor air-pollution levels inside the home, he added.
To improve the air quality in her new Charleston, S.C., home, Caroline Smythe, 67, imported a hemp block covered in a mixture of lime and sand for the construction, rather than standard brick. Living in a high-humidity area means moisture can cause mould, said Smythe, whose 2,400-square-foot Lowcountry home was completed in 2023 for about $1 million, including $250,000 for the land.
Incorporating the new material allows the moisture to get absorbed in the walls and keeps humidity steady in the home. “It has very much an earthy feel,” said Smythe of her thick, soundproof walls.
Inside, the home’s two bedrooms and two offices have additional air-filtration elements, including stand-alone air filters for each bedroom. Smythe, a psychiatrist, chose a bamboo kitchen countertop and mineral-based wall paint to prevent any chemical off-gassing. “It makes a huge difference,” she said.
Homeowners have long tried to improve air quality. In the early 1900s, homes that let in fresh air were critical to good health, but by the 1950s some owners were trying to tame outdoor air pollution by focusing on better insulation. More recently, the pandemic made access to outdoor air essential, and turned the focus again to indoor-outdoor living.
Today’s picture is mixed. Climate change has made outdoor air quality less reliable, with the added problems of prolonged forest fires.
Many people are realising their indoor air quality is often compromised by a combination of poor indoor airflow, activities like cooking and cleaning, and outdoor pollutants that settle into confined spaces, said Gall. Homeowners now want better control over their wider living space, including modifiable systems that deal with both indoor and outdoor pollution, he added.
Jason Glatt, a commercial window contractor, and his wife, Lauren Glatt, a stay-at-home mom, of North Bethesda, Md., built a $2.5 million home that includes a children’s slide into a basement playroom, an attic-level cigar room and plenty of entertaining space.
The 11,000-square-foot home’s most striking feature, however, may be the five HVAC units tucked inside utility closets and other closed rooms, controlled by eight thermostats that regulate the air quality as well as temperature in each part of the home. Their $120,000 HVAC system also includes UV lights to prevent mould.
Seth Ballard, an architect who worked with the Glatt family, said individually controlled temperature zones and more return-air vents promote better air flow. Costs can be $100,000 to $200,000 for a 10,000- to 15,000-square-foot house. “They are choosing this over a kitchen countertop,” he said of homeowners in general.

Charlotte of the Upper West Side, a building in Manhattan that opened in 2023, has seven full-floor units, each with a private entrance. The building has airtight construction with enhanced insulation. Each unit has an independent heating-and-cooling system with fresh-air filtration directly into the home that isn’t shared with other spaces.
The system can achieve full air exchange 13 times a day in normal-use mode and more than 28 times a day in boost mode, said the building’s developer John Roe of the New York-based Roe Corp. The building uses louvers outside the windows to deflect the heat of the sun and cut energy use on summer days.
Roe, who lives in one of the building’s 3,570-square-foot, four bedroom, 4.5-bathroom homes, said the air-filtration system and strict passive-home construction added 15% to the building cost.
Three of the building’s units are on sale, from $8.35 million to $17 million.
He said there is little dust in the home, and he swears it now takes longer for his cut white hydrangeas to wilt.

On Bastille Day, the scent of toasted bread, melting cheese, crêpes and velouté filled a heritage warehouse in Sydney’s Darlinghurst.
Inside Prim Haus, rooms had been transformed into an elegant interpretation of a contemporary French home. Cookware hung alongside market produce, appliances were placed within carefully composed domestic settings and live kitchens turned out French comfort food throughout the afternoon.
The occasion was La Maison de Tefal, an immersive celebration marking 70 years since a French engineer introduced an invention that would fundamentally change home cooking.
Tefal’s story began in 1956 with the commercial launch of what the company describes as the world’s first non-stick frying pan. Seven decades later, the business operates across cookware, kitchen appliances, garment care and floor care in more than 120 countries.
The scale of the modern brand is considerable, but its origins were remarkably domestic.
The invention that started in a French kitchen
In the early 1950s, French engineer Marc Grégoire began experimenting with polytetrafluoroethylene, better known as PTFE, after discovering its unusually effective non-stick properties.
The material was already known within industrial applications. Grégoire’s important contribution was developing a way to bond it securely to an aluminium disc.
According to the company’s history, a conversation with his wife inspired him to apply the process to cookware. The resulting pan allowed meat and eggs to be cooked using less fat, while making the surface considerably easier to clean.
Grégoire patented his non-stick frying-pan concept in 1954 and began selling the finished product in 1956. The new company’s name combined the French words for the two defining materials: Téflon and aluminium.
The attraction was immediate. This was innovation expressed through a simple, recognisable household problem. Food stuck to pans; the new Tefal pan was designed so it would not.
The idea quickly travelled beyond France. Tefal entered the United States in 1961, the same year the company established the production site at Rumilly, near the French Alps. Rumilly would become the centre of Tefal’s cookware expertise and develop an identity as the “frying pan capital of the world”.
The company says more than 35 million cookware items were manufactured at the Rumilly site in 2022. A local museum holds the 500 millionth pan produced by the factory, which came off the line in March 1994.
A Parisian home in the heart of Sydney
La Maison de Tefal translated that industrial history into a more intimate experience.
Held on 14 July, the anniversary used Bastille Day as both a cultural reference and a reminder that Tefal’s identity remains closely connected to French design and engineering.
Prim Haus was arranged as a sequence of domestic environments rather than a conventional product showroom. Guests moved through spaces devoted to cookware, kitchen appliances, garment care and floor care, with each collection presented within the rhythm of a modern home.
A French-market-inspired cooking area formed the social centre of the event. Live stations served croque-monsieur, crêpes and butternut velouté, demonstrating the products through food rather than static displays.
That distinction matters. Tefal’s most successful products have generally been those whose benefit can be understood almost immediately: a pan that releases food, a removable handle that saves cupboard space, an indicator showing when cookware has reached the correct temperature, or an appliance that automates part of a familiar cooking process.
Interactive demonstrations allowed guests to handle the products and see those functions in context. Heritage installations traced the brand’s development, while previews of newer releases connected its first frying pan with the much broader contemporary range.
The anniversary concluded with a champagne toast — an appropriately French punctuation mark for a company whose products have found their way into kitchens around the world.
Seventy years of practical invention
The non-stick frying pan established the operating principle Tefal continues to follow: find an everyday source of friction and develop a practical way to reduce it.
In 1996, the company introduced Ingenio, a modular cookware system built around removable handles. Pans could be stacked more efficiently and moved from cooktop to oven, table and refrigerator without the fixed handle of conventional cookware.
The concept anticipated the pressures that would reshape urban kitchens. As apartments became more compact and storage more valuable, cookware needed to occupy less room and serve more than one function.
Around the beginning of the following decade, Tefal introduced its heat-indicator technology, now known as Thermo-Signal. The circular marker changes appearance when the pan reaches its recommended cooking temperature, turning a technical question into a visual prompt.
In 2006, Tefal expanded the possibilities of countertop cooking with ActiFry. The appliance circulated hot air around food and used little or no added oil, helping establish a product category that would eventually become one of the most competitive areas of the global appliance market.
Innovation also moved beyond cooking. The Freemove cordless steam iron arrived in 2012, removing the cord from the active ironing movement while retaining a powered base.
The company’s current portfolio now extends across multicookers, grills, air fryers, blenders, ice-cream makers, garment steamers, irons and floor-care products. Although the categories are diverse, the common proposition remains convenience grounded in engineering.
The next generation of non-stick cookware
For its 70th year, Tefal has returned to the product that created the brand.
The new Excellence+ cookware range introduces what the company calls FusionCore technology. Tefal describes it as its most durable non-stick coating to date, designed to withstand intensive use and scratching.
As with any durability claim, consumers should follow the manufacturer’s care instructions and consider the applicable warranty rather than interpreting promotional language as a guarantee against every form of damage. But the focus on longer-lasting coatings reflects an important change in buyer expectations.
Convenience is no longer enough on its own. Modern households are increasingly concerned with how long products remain useful, whether they can be repaired and what happens when they reach the end of their working life.
Tefal has responded in several ways. Its Renew cookware uses recycled aluminium and a ceramic non-stick coating, while Groupe SEB has expanded cookware recycling initiatives in international markets. For many small domestic appliances, the group also promotes a 15-year repairability commitment based on parts availability and access to authorised repairers.
The details and warranty periods vary by product and country, so Australian buyers should check the conditions attached to an individual appliance. Nevertheless, repairability represents a meaningful shift from the assumption that a failed countertop appliance should simply be discarded.
From French manufacturer to global household group
Tefal joined Groupe SEB in 1968, giving the company greater international distribution and the resources to expand beyond cookware.
Founded in 1857 and headquartered in France, Groupe SEB has grown into a global small-appliance and cookware business with more than 30 brands. Its portfolio includes All-Clad, Krups, Moulinex, Rowenta, Lagostina and WMF, with operations extending across more than 150 countries.
Within that group, Tefal remains one of the flagship names — and one of the clearest examples of how a single invention can become the foundation for an international consumer brand.
Its longevity has not come from making everyday objects more complicated. The strongest Tefal products do the opposite. They take a small uncertainty, inconvenience or frustration and design it out of the task.
That was the value of Marc Grégoire’s original frying pan. It did not ask people to change what they cooked. It made the existing process easier, more predictable and less difficult to clean afterwards.
Seventy years later, that deceptively modest principle continues to guide the company.
La Maison de Tefal celebrated the products, the French heritage and the anniversary itself. Yet the larger story was visible at every cooking station and demonstration: innovation becomes lasting only when people can use it without having to think about the technology underneath.
For Tefal, the next 70 years will be shaped by new materials, smarter appliances, changing homes and greater expectations around durability. Its challenge will be to keep evolving without losing sight of the insight that started everything — that the most valuable household inventions often solve the most ordinary problems.
