If you are upgrading to a full-size American fridge freezer, you are probably looking for more space, less faff and something that looks the part in a modern kitchen. The Hisense PureFlat Infinite RQ758N4SASE Total No Frost American Fridge Freezer in stainless steel is a good example of what this new generation of appliances offers: clean styling, big capacity and no-ice cooling. In this guide we will use it as a reference point to explore what to look for in a large fridge freezer, how to plan the space properly, and which close alternatives are worth a look if your priorities or kitchen layout are a little different.
Why the Hisense PureFlat Infinite RQ758N4SASE stands out
The Hisense PureFlat Infinite RQ758N4SASE is a four-door American fridge freezer finished in stainless steel, with a flat front that suits contemporary kitchens. It is designed around a Total No Frost system, so it keeps both fridge and freezer free from icy build-up. With a sky-high user rating of 4.9 from more than 3,000 buyers, it clearly hits the mark for many UK households.

Measuring up: will a large American fridge freezer fit your kitchen?
Before falling for the sleek look of a PureFlat design, it is crucial to check the basics. American fridge freezers are deeper and wider than standard 60 cm full-height models, and their doors need enough swing space to open fully.
Start by measuring:
- Width: allow for the body of the fridge plus a small gap either side for ventilation.
- Depth: include handles and any door curvature if relevant, then compare with your worktop and walkway space.
- Height: make sure there is room above so warm air can escape and you can clean the top occasionally.
The Hisense PureFlat Infinite RQ758N4SASE is a substantial appliance, so it suits medium to large kitchens best. If you are fitting it into an alcove, check the manufacturer’s minimum clearances in our detailed technical breakdown: you will find those in the dedicated product write-up when you visit the full RQ758N4SASE review page.
Understanding layouts: four-door vs side-by-side
The RQ758N4SASE uses a four-door layout with French-style doors at the top and separate freezer zones below. This gives you wide shelves in the fridge area, which is ideal for party platters, baking trays and large salad bowls. The freezer sections are more compartmentalised, often with drawers and shelves that make it easier to separate frozen veg, meat and batch-cooked meals.
If you like this general approach but are happy to go for a more traditional side-by-side design, the Hisense RS694N4IBE is worth considering. It puts fridge and freezer in tall, vertical columns. The fridge section is a little narrower but offers plenty of door storage for bottles and jars, and it can be easier to view frozen food at eye level rather than rummaging in deep drawers.
Another close relative is the Hisense PureFlat RQ758N4SAFE, which keeps the same four-door PureFlat design language as the RQ758N4SASE but comes in a black and stainless mix for a slightly bolder look. If you are torn between finishes, imagining how often you will see fingerprints and how much daylight your kitchen gets can help tip the balance.
Total No Frost: why it is more than a buzzword
Total No Frost is one of the main reasons shoppers move up to a modern American fridge freezer. In a model like the Hisense PureFlat Infinite RQ758N4SASE, chilled air is circulated evenly, preventing ice from forming on evaporator coils and the inside walls. That means no more defrosting weekends, no frosty drawers and more stable temperatures around your food.
Hisense extends this idea across much of its American range. The Hisense PureFlat Infinite RS818N4TFE, for example, also uses Total No Frost but combines it with smart connectivity and a different door arrangement. Likewise, the Hisense PureFlat RQ5P470SAFD offers Total No Frost alongside Wi-Fi controls and a black stainless finish.
If you are upgrading from a much older fridge freezer that ices up regularly, the difference Total No Frost makes to daily convenience is significant. Food labels stay readable, drawers slide without sticking and your freezer storage is much easier to keep organised.
Energy rating and running costs: what E means in real life
Energy labels were overhauled in recent years, which is why many large appliances now sit in the D–F band when older models used to show A+, A++ or A+++. The Hisense PureFlat Infinite RQ758N4SASE is classed as E rated, which is typical for an American fridge freezer of this size.
In practice, the main factors that affect how much you pay to run it are:
- How often the doors are opened and how long they are left ajar.
- Room temperature and direct sunlight on the doors.
- Whether there is enough clearance for heat to escape.
- How well you keep the vents and door seals clean.
Alternatives like the RS818N4TFE, RS694N4IBE and RQ5P470SAFD also sit in the same energy ballpark, with E or nearby ratings. If you are chasing the absolute lowest running cost, you might look for a slightly smaller D-rated model such as the RQ5P470SAFD, which pairs a generous capacity with a more efficient label. However, the difference on your annual bill between comparable E and D models is often modest, so it is worth balancing running costs with storage, features and layout that genuinely suit your household.
Water, ice and connectivity: which extras are worth paying for?
Once you know how much space you have and what layout you prefer, it is time to think about extras. Models around the RQ758N4SASE’s price tend to offer a mixture of water dispensers, ice makers and in some cases Wi-Fi connectivity.
Plumbed vs non-plumbed dispensers
If you want chilled water and ice on tap, you need to decide whether you are happy to run a water line to your fridge. The Hisense RS694N4IBE is a plumbed model, which means you get constant filtered water and ice without refilling a tank. That is ideal if your fridge will live against an outside wall or near existing pipework.
For more flexibility on placement, the Hisense PureFlat Infinite RS818N4TFE is non-plumbed, using an internal reservoir that you top up manually. This avoids the cost and disruption of plumbing but still gives you the convenience of a dispenser on the door.
The RQ758N4SASE focuses on its spacious compartment layout and Total No Frost cooling; if you are less bothered about a dispenser and more interested in flexible storage, that trade-off may suit you just fine.
Smart features and Wi-Fi
Wi-Fi enabled models like the Hisense PureFlat RQ5P470SAFD and RS818N4TFE add app-based controls to the mix. You can usually adjust temperatures, switch on holiday modes or get alerts if the door has been left open.
For some households that is a nice-to-have; for others it becomes genuinely useful, especially if the fridge is in a utility room or garage where you might not hear alarm beeps. If you prefer a simpler, set-and-forget approach, a non-connected model like the RQ758N4SASE keeps things more traditional.
Finish and style: stainless vs black and PureFlat vs curved
Large American fridge freezers dominate the room, so choosing the right finish makes a big difference to how your kitchen feels. The Hisense PureFlat Infinite RQ758N4SASE wears a stainless steel look that blends well with other metallic appliances and hides day-to-day scuffs fairly well. The flat doors emphasise straight lines and pair nicely with handleless cabinets and modern lighting.
If you want something bolder, the Hisense PureFlat RQ758N4SAFE offers a black and stainless combination that looks striking against light-coloured units. For a fully darker aesthetic, the RS694N4IBE in black might be more your taste.
Think about fingerprints, too. Dark gloss and glass can show smudges more than brushed finishes, while lighter steel can be a little more forgiving. Microfibre cloths and a good stainless cleaner will quickly become your friends whichever finish you choose.
Storage ideas: making the most of a big-capacity fridge freezer
Once your new fridge freezer is in place and chilled, it is tempting to just load everything in and shut the doors. Spending a few minutes planning your zones will keep food fresher for longer and make life easier.
- Use the top shelves for leftovers, ready-to-eat items and jars you reach for often.
- Keep raw meat and fish on the lowest shelves in case of drips.
- Put snacks and drinks at eye level if you have teenagers raiding the fridge constantly.
- Reserve one freezer drawer for quick midweek items and another for longer-term storage.
The four-door layout of the Hisense PureFlat Infinite RQ758N4SASE lends itself well to this kind of zoning. You can dedicate one lower section more towards everyday frozen items and the other to bulk buys or batch cooking. Similar logic applies to the RQ758N4SAFE and RQ5P470SAFD, which share the PureFlat multi-door approach.
Installation, delivery and first-day tips
A common surprise with American fridge freezers is simply getting them through the front door. Before delivery day, measure your hallways, doorways and any tight corners. In many cases, doors and sometimes even internal drawers can be removed temporarily to squeeze through narrow gaps, but it is much less stressful to plan this in advance.
Once in position, allow the appliance to stand upright for a few hours before switching on, especially if it has been tilted during transport. After you power it up, give it the recommended time to reach the correct temperature before loading it with food; this is usually several hours or overnight for large models. Check that doors seal properly, the appliance is level and any ice or water dispensers are working as expected before you fill every shelf.
Which Hisense American fridge freezer is right for you?
You do not need to memorise model numbers to make a good choice. Think in terms of layout, extras and finish, then match a Hisense model to those priorities:
- Want a four-door PureFlat design with Total No Frost and a stainless finish? The Hisense PureFlat Infinite RQ758N4SASE is the one to focus on.
- Like the RQ758 layout but prefer a darker, two-tone look? The Hisense PureFlat RQ758N4SAFE is the closest alternative.
- Prefer side-by-side doors and plumbed water/ice? Take a look at the Hisense RS694N4IBE.
- Want PureFlat styling plus non-plumbed dispenser and Wi-Fi? The Hisense PureFlat Infinite RS818N4TFE is designed for you.
- Looking for a slightly more efficient D-rated option with Wi-Fi and a stylish black stainless finish? The Hisense PureFlat RQ5P470SAFD is well worth considering.
Each of these models shares the same general ethos: spacious interiors, Total No Frost and a focus on modern styling. The differences lie in how you access that space, how connected you want the appliance to be, and whether plumbing in is practical.

Choosing a large American fridge freezer is as much about how you live as it is about litres and labels. The Hisense PureFlat Infinite RQ758N4SASE makes a strong case with its four-door layout, stainless steel PureFlat design and excellent user feedback, but the wider Hisense line-up shows there is room to tailor the details to your own kitchen and habits.
